3、r by adding the Snap and Quick Translate Ergonomics Design select the Engine from the PPR Tree. ( That way all of the components that create the engine are selected.) 6. The command prompt asks select on component the first geometric element, Click on the Surface on the bottom of the engine. Notice
4、that the pointer changes from line, plane. When it shows plane ( box as shown). The S nap icon appears in the workbench. Ergonomics Design select Hide/Show in the View toolbar. Notice that the Icon in front of the workbench is grayed out. ( Easy way to check if something is hidden) 14. Where did thi
5、s hidden object go? This command hides the selected object by transferring it to the Swap Visible Space viewing window. Click the Swap visible space icon to display the objects. Here is the workbench, and all of the segments, line of sight for the Ergonomics Design rotate Matt to see his left side.
6、In the Manik in Posture Toolbar, we have a contextual Toolbar. Inverse Kinematics Mode. Inv erse Kinematics (IK) Segment Frame Mode IK Segment Frame mode In this mode, any segment selection made in the 3D environment will automatically snap the compass to the associated segment IK control point. The
7、 compass is oriented in the segment frame. A yellow hand appears which shows the position of the move. Inv erse Kinematics (IK) Worker Frame Mode IK Work er Frame mode This mode behaves in the same manner except the compass is oriented in the worker ( global) frame. A yellow hand appears which shows
8、 the position of the move. Ergonomics Design that central spot is represented by a circle Ergonomics Design the contextual menu appears as follows: Use the Constraints check boxes to “freeze“ the positions of the hands and the direction of vision while the rest of the manikin is moving. This option
9、cannot be used in the Hand Grasp and the Adjust Elbow tabs. The Display function contains the Animate Viewpoint option. This option zooms on the manikin and changes the viewpoint in order to provide the best possible view of the working posture. Procedure:Procedure:Procedure:Procedure: In this exerc

The Attach/ Detach v erification window appears. Click on OK. In the directory, Cheryl positions, there is a pu lling ou t drawer pose
12、 for ease Hu man Bu ilder Facilitated Project: Manikins with an Engine and Workbench Creating a Track Ergonomics Design select the manikin (Cheryl) left hand segment for the Object. Left Hand appears in the Object field, the name changes, of the dialog box and the Manipu lation toolbar appears. We w
13、ill u se the standard defau lt in the Manipu lation. 6. In the Interpolater combo field, select the linear interpolater, (ev en if it is shown, select it again, and notice that the compass orientation changes) and the Speed 5m_s. 7. The 3D compass attaches to the hand in the defau lt position for th
14、at segment. 8. Using the compass, grab and Drag the Drawer.1 ou t, and Click on the Record Icon. In the Recorder dialog box, click on OK to finish the track. Ergonomics Design constraints are created through the constraints creation command. These commands in the Manikin Constraints toolbar give you
15、 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
16、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). Procedu
17、re:Procedure: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. Human Builder Facilitated Project: Manikins with an Engine and Workbench Manikin Constraint
18、s Ergonomics Design & Analysis V5R12SP2 hmb.doc 55 of 96 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 creates a constraint between
19、a segment and a line or a plane. c. The Fix On 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 manikin referential or a given object. d. The Fix Constraint command constrains the segment i
20、n 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 and you must select the Update icon in the Manikin Constraints toolbar each time you want to update t
21、he 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
