CLEVELAND STATE UNIVERSITY CE#26-MOTION STUDIES: SUMMARY: Motion Studies are used to create animations in SolidWorks. They use a timeline-based interface to animate motion, cameras, lights, appearances, suppressions, and other elements of an assembly. Motion studies do not change assembly properties but their motions are limited to them i.e. what can be moved in an assembly is what can be animated. There are 3 types of motion modes: animation, basic motion, and motion analysis. Animation mode provides basic motion using keyframes and motors. Basic motion mode provides more realistic simulations using springs, advanced mates, and gravity. Motion analysis mode is part of the SW Motion add- in that uses kinematic solvers that account for material properties such as mass/inertia to simulate advanced motion based on forces, springs, dampers, and friction. This exercise will cover the animation mode only. INSTRUCTIONS: Use motion studies to create an animation of the tricone drill that is shown in ce#26-end.wmv. HOM figure ce#26-01: Tricone drill model Page 1/10 1. Open the start file: 1.1. Open the ce#26 start.sldasm file. 1.2. Look for a tricone drill appear in the graphics area.. 2. Activate the [FREE FOR ALL] configuration: note: The default model is restrained to a [TEMP ALIGN RIGHT] and [TEMP ALIGN FRONT] mate. The [FREE FOR ALL] configuration will suppress those mates so the model can rotate and translate as needed for the animation. Remember that an assembly can only be animated where the assembly moves freely. 2.1. Go to the configurations tab and double click [FREE FOR ALL]. Make sure not to move the assembly parts around after this step is done since the alignment will be lost.

Go to Insert > Exploded View, or search it from the command box. 3.2. Sequence the exploded parts as if they were disassembled in real life. See the chart below for translate/rotate values and explode as shown.

Make sure not to edit the explosion in the model after a motion study is created because this can damage the animation and it is often irreversable. 3.4. See ce#11-assembly drawings if assistance is needed with explosion views. 4. Setup a motion study: 4.1. Select the Motion Study button on the lower tabs. Model 3D Views Motion Study 1. 4.2. If changes were made to the assembly, it's best to create a new motion study. To create a new motion study, right-click the lower tabs, and select [Create New Motion Study]. Duplicate Rename Create New Motion Study Create New Design Study 4.3. Right-click the [Orientation and Camera Views] item and select [Disable Playback of View Keys].

Set the [Camera type] to [Aimed at target], a view angle of 35°, and position the camera as shown in the screenshot. The camera can be positioned in either graphic area. 5.3. See ce#20-photoview for assistance on cameras. 6030 000 2 Page 4/10 ☑ 6. Animate the collapse: 6.1. Select the Animation Wizard tool from the motion study toolbar. 6.2. Select [Collapse] for [Type of animation], select [Next], enter 4 for [Duration(seconds)], 0 for Start Time(seconds), and select [Finish]. Rotate model To control the speed of the animation, set the duration of the entire animation below. Duration (seconds): 4 Explode Collapse To delay the movement of objects at the beginning of the animation, set the start time. Start Time (seconds): 0 6.3. For all part(s) that were rotated in the explosion step, select its set of keyframes, right- click, and select [Reverse Path]. This is to correct the orientation, it's not required for animating an explosion.
