Ergonomics Design & Analysis Facilitated Project: V5R12SP2 Manikins with an Engine and Workbench Starting a Project Human Builder Scope: Scope: Human Builder is based on a best-in-class human modeling system, which, for many years, has permitted detailed investigation into human-centered design issues in the context of a workplace before it physically exists. Human Builder provides very accurate simulation of humans and their interactions with products to ensure they will operate naturally in a workplace tailored to their tasks. The Human Builder product specifically focuses on creating and manipulating digital humans for \"first level\" human-product interaction analysis. Human Builder consists of a number of advanced tools for creating, manipulating and analyzing how manikins (based on the 5th, 50th and 95th percentile value) can interact with a product. The manikins can then be used to assess the suitability of a product for form, fit and function. The manikins can be intuitively created and manipulated in conjunction with the digital mockup to check features such as reach and vision. A simple-to-use interface ensures that first-level human factors studies can be undertaken by non-human factors specialists. Tools contained within the Human Builder product include manikin generation, gender specification, percentile specification, direct kinematics and inverse kinematics manipulation techniques, animation generation, monocular, binocular and ambinocular vision simulation, as well as vision output cones. Since this deals mostly with the relationships of the Manikins, there is no process, as it deals with the functions of the manikins, therefore it is created as a Product, not a Process. Procedure: Procedure: In this procedure we will review the basics of starting a project. 1. Depending on the previous workbench, the software will default to that one. For our example, make sure that we hmb.doc 1 of 96 Ergonomics Design & Analysis V5R12SP2 have the Ergonomics Design & Analysis workbench, Human Builder. 2. With the software open, select File/ New and the New dialog box appears. Scroll down, and select Product and OK. The workbench Icon always appears in this corner (unless moved) This is a good quick view “check” for what workbench you are in 3. Notice all of the icons along the sides of the software; we will review those later in the session. We will insert a product and a resource. 4. Select in our Menu bar Insert / Existing Component, and click on the word Process in our PPR Tree. hmb.doc 2 of 96 Ergonomics Design & Analysis V5R12SP2 5.

Manikin: The Manikin field remains empty until you select the desired manikin. To make the selection, click with the left mouse button directly on the manikin or select the manikin from within the product tree. The selected manikin's name will appear in the Manikin field to confirm your selection. You can select manikins continuously while this command is running. Each selection will cancel the previous one and the Manikin field will be updated with the name of the newly selected manikin. Three types of manikin displays are available: segments, ellipses, and surfaces. • • To change the manikin display, select the display type with the appropriate toggle button. Various display types can be selected at the same time. Center of gravity The center of gravity cannot be manipulated. However, the center of gravity's position automatically updates when any segment is manipulated. hmb.doc 25 of 96 Ergonomics Design & Analysis Segments Ellipses V5R12SP2 Resolution Resolution represents the number of points taken on each ellipse to draw the surfaces at manikin creation. The default value of this parameter is 32 but it can vary from 4 to 128. Low resolution: High resolution: hmb.doc 26 of 96 Ergonomics Design & Analysis V5R12SP2 Line of sight The line of sight is designed to facilitate the manipulation of the manikin's vision.

Facilitated Project: V5R12SP2 Manikins with an Engine and Workbench Creating a Catalog for our Products and Manikins Human Builder Scope: Scope: In this procedure we will review how to create a Catalog. The products have been drawn, and saved in the Catalog file folder. The reason that we store our 3D objects, is that the catalog is stored in the PPR Hub, and when we want to use these products in other projects, they are stored conveniently and quickly for reference or retrieval. Users often need a way of storing and classifying the many objects they have at their disposal, whether they are screws, ball bearings or computer parts. These objects may number tens of thousands, each with its own specific characteristics such as shape, color, size, diameter, length, standard, etc. To facilitate fast and easy retrieval of such objects thus avoiding time-wasting redesign Version 5 offers the possibility of creating catalogs (identified by the .catalog extension). These can either be created from scratch or through the conversion of CATIA Version 4 libraries. A Version 5 catalog is in the form of a tree structure made up of: chapters: a chapter references other chapters or families. It is a way of classifying the elements it refers to families (end chapters): a family is a set of components part families: a part family is a set of components referring to a .CATPart document. This part is unique but has been assigned different sets of parameter values, each of them being managed by a design table components: a component is a reference to an external document or an entity such as a feature (e.g. PowerCopy), V4 documents (e.g. models) or V5 documents (e.g. CATPart, CATProduct, etc.) described with keyword values keywords: a keyword is an attribute describing the chapter and family content. Each component may be assigned its own attribute value. You can associate keywords to chapters and families and thus, perform searches by attribute value to filter their content. hmb.doc 30 of 96 Ergonomics Design & Analysis V5R12SP2 The example shown below and elucidated in some of the following tasks is a generic family comprising bolts, i.e. a chapter ALL_FASTENERS referencing end chapters (SCREWS and NUTS) which, in turn, reference entities. The entities referred to by the end chapters can be described using keywords such as Diameter, Length, Designation, etc. Procedure: Procedure: In this exercise, we will create one catalog for our resources and one for the manikins 1.

We have the selection of saving different formats. The Global posture saves the entire Manikin segments, and the position in the workspace. The Local posture saves the posture of the selected segment, e.g., the right arm. The vision saves the vision settings, and finally the manikin Anthropometry can also be saved into a library. “Position will keep the absolute coordinate within the scene”. 4. Let’s create a few more poses for Cheryl. One with her sitting back in the chair, with her hands placed on the sides of the chair, and her head rotated so she is looking forward. Save this pose in the Library as Relaxing in Chair. hmb.doc 50 of 96 Ergonomics Design & Analysis V5R12SP2 5. Use the Posture Editor, and select Cheryl and at the bottom of the editor, select the pose Sitting. Then we will have to rotate her so that she is sitting straight.

Click on the manikin Cheryl, and select Pulling out the drawer, Apply, Close. hmb.doc 53 of 96 Ergonomics Design & Analysis V5R12SP2 Facilitated Project: Manikins with an Engine and Workbench Manikin Constraints Human Builder Scope: Scope: The Human Builder workbench lets you create manikin constraints, which specify explicitly how the geometries should behave. A constraint applies to the manikin and geometry; constraints are created through the constraints creation command. These commands in the Manikin Constraints toolbar give you the capability to constrain the manikin in its environment. With constraints, the manikin can perform inverse kinematics (IK) to calculate the necessary posture needed to reach multiple specific targets. A constraint will always belong to one manikin. At any given time, the list of constraints on a manikin will appear underneath that manikin in the specification tree. Inactive constraints will also be listed. At any time, you may update the active constraints at each modification in the workspace (automatic update), or only update the active constraints when needed (manual update). Procedure: Procedure: In this example, we will create a constraint between the Manikin and the screwdriver. 1. With the manikin’s hand over the screwdriver, select the Manikin Constraints Toolbar. hmb.doc 54 of 96 Ergonomics Design & Analysis V5R12SP2 2. This toolbar has 4 different types of Constraints, and the update. a. The Contact Constraint command creates a constraint between a segment and a point, a line, or a plane. b. The Coincidence Constraint command between a segment and a line or a plane. c. The Fix On Constraint command constrains the segment in creates a constraint orientation and in position (or only in orientation or only in position) at its current position according to the manikin referential or a given object. d. The Fix Constraint command constrains the segment in orientation and in position (or only in orientation or only in position) at its current position, according to the selected object. e. By default, constraint update mode is set in the Manual mode in the Manikin and you must select the Update icon Constraints toolbar each time you want to update the active constraints and resolve the inverse kinematics. If you want it to automatically update, in Tools / Options / Ergonomics Design & Analysis / Human Builder / General Tab / Constraint Resolution (Manual / Automatic). Leave the default, manual for now. 3. Select the Contact Constraint icon. 4. Select Matt’s Hand, and then the Blue part on the Wrench.

Facilitated Project: Manikins with an Engine and Workbench Attaching and Redefining the offset to the Screwdriver 83 of 96 Human Builder hmb.doc Ergonomics Design & Analysis V5R12SP2 Scope: Scope: The attach function creates a one-way relationship between a manikin segment and one or more objects in its environment. The attached object becomes a slave to the segment. Once attached, this object will move with the same matrix as its master segment. The Offset command is used to redefine the behavior of the Reach Mode. The Reach Mode's default behavior is to make the end point of the selected segment or skin point reach the compass location. The Offset command allows you to transfer that \"end point\" to another point in the 3D space, which will then be used to perform inverse kinematics. An example of this would be when the manikin must perform some inverse kinematics while handling an object. In redefining the offset, the compass may be also be snapped to manikin skin points. Thus, the subsequent reach operation is resolved from the skin rather than the central point of the segment. Procedure: Procedure: In this procedure we will attach the Screwdriver to his hand and redefine the offset to the end of the screwdriver. 116. Restore the Manikin so that the engine is on the table by using in the Opens a human library icon. 117.
