Dashboard Mode - Assembly motion study basics
Business Question

How can we analyze the movement and interaction of parts in an assembly to ensure smooth operation and detect potential issues?

Sample Data: Assembly Motion Study Results
Step Time (s) Part Displacement (mm) Velocity (mm/s) Interference Detected
10Gear A00No
21Gear A1010No
32Gear A2010No
10Lever B00No
21Lever B55No
32Lever B1510Yes
43Lever B205Yes
Dashboard Components
  • KPI Card: Total Steps - Shows the total number of motion steps (4 steps)
  • KPI Card: Interference Count - Counts how many steps have interference detected (2 steps)
  • Line Chart: Displacement Over Time - Plots displacement (mm) vs. time (s) for each part (Gear A and Lever B)
  • Bar Chart: Velocity by Step - Shows velocity (mm/s) for each step and part
  • Table: Detailed Motion Data - Displays all columns from the sample data for review

Interactivity

A filter allows selecting a specific part (Gear A or Lever B). When a part is selected:

  • KPI cards update to show steps and interference count only for that part.
  • Line chart and bar chart update to show data only for the selected part.
  • The detailed motion data table filters to show only rows for the selected part.

Self Check

Add a filter for Part = 'Lever B'. Which components update?

  • Total Steps KPI updates to 4 (steps for Lever B)
  • Interference Count KPI updates to 2 (steps with interference for Lever B)
  • Line Chart shows displacement over time only for Lever B
  • Bar Chart shows velocity by step only for Lever B
  • Detailed Motion Data table shows only rows for Lever B
Key Result
Dashboard shows assembly motion steps, displacement, velocity, and interference detection for parts Gear A and Lever B.

Practice

(1/5)
1. What is the main purpose of an assembly motion study in SolidWorks?
easy
A. To visualize how parts move together in an assembly
B. To create 3D models from 2D sketches
C. To generate technical drawings automatically
D. To calculate the weight of individual parts

Solution

  1. Step 1: Understand the function of motion study

    Assembly motion study is used to see how parts move and interact in an assembly.

  2. Step 2: Compare options with this function

    Only To visualize how parts move together in an assembly describes visualizing part movement, which matches the purpose.

  3. Final Answer:

    To visualize how parts move together in an assembly -> Option A

  4. Quick Check:

    Assembly motion study = visualize part movement [OK]
Hint: Think: motion study means showing movement [OK]
Common Mistakes:
  • Confusing motion study with drawing creation
  • Thinking it calculates weight or mass
  • Assuming it creates 3D models from sketches
2. Which of the following is the correct first step to create a motion study in SolidWorks?
easy
A. Open the Motion Study tab at the bottom of the assembly window
B. Export the assembly as a STEP file
C. Create a new part file
D. Run a simulation analysis from the Simulation tab

Solution

  1. Step 1: Identify how to start a motion study

    Motion studies are started by selecting the Motion Study tab in the assembly interface.

  2. Step 2: Eliminate unrelated options

    Exporting files, creating parts, or running simulation analysis are not the first step for motion studies.

  3. Final Answer:

    Open the Motion Study tab at the bottom of the assembly window -> Option A

  4. Quick Check:

    Start motion study = open Motion Study tab [OK]
Hint: Look for the Motion Study tab in the assembly window [OK]
Common Mistakes:
  • Trying to export files before starting motion study
  • Confusing motion study with simulation analysis
  • Starting with a new part instead of assembly
3. Given this simple motion study setup: a gear rotates 90 degrees over 5 seconds. What is the angular velocity in degrees per second?
medium
A. 450 degrees per second
B. 90 degrees per second
C. 18 degrees per second
D. 0.18 degrees per second

Solution

  1. Step 1: Identify total rotation and time

    The gear rotates 90 degrees in 5 seconds.

  2. Step 2: Calculate angular velocity

    Angular velocity = total rotation / time = 90 / 5 = 18 degrees per second.

  3. Final Answer:

    18 degrees per second -> Option C

  4. Quick Check:

    90° ÷ 5s = 18°/s [OK]
Hint: Divide total degrees by total seconds for velocity [OK]
Common Mistakes:
  • Multiplying instead of dividing degrees by time
  • Confusing degrees with radians
  • Ignoring the time duration
4. You created a motion study but the parts do not move as expected. Which of these is the most likely cause?
medium
A. The computer does not have enough RAM
B. The assembly file is saved in the wrong folder
C. The parts are missing color textures
D. The mates between parts are not properly defined

Solution

  1. Step 1: Identify what controls part movement

    Part movement depends on mates that define how parts connect and move relative to each other.

  2. Step 2: Evaluate other options

    File location, colors, or RAM do not directly affect motion study movement.

  3. Final Answer:

    The mates between parts are not properly defined -> Option D

  4. Quick Check:

    Movement depends on mates = correct mates needed [OK]
Hint: Check mates first if parts don't move [OK]
Common Mistakes:
  • Blaming file location for motion issues
  • Thinking textures affect movement
  • Assuming hardware issues cause no movement
5. You want to simulate a door opening in an assembly. Which combination of steps will best create a realistic motion study?
hard
A. Use the explode tool to separate the door from the frame
B. Add a hinge mate, set rotation limits, and apply a motor to rotate the door
C. Create a new part for the door, then run a stress analysis
D. Add a fixed mate, color the door, and export as animation

Solution

  1. Step 1: Define realistic movement with mates

    A hinge mate allows rotation like a real door hinge.

  2. Step 2: Control motion and automate it

    Rotation limits prevent unrealistic movement; a motor applies controlled rotation.

  3. Step 3: Eliminate incorrect options

    Fixed mates prevent movement; coloring or exploding parts do not simulate motion realistically.

  4. Final Answer:

    Add a hinge mate, set rotation limits, and apply a motor to rotate the door -> Option B

  5. Quick Check:

    Hinge + limits + motor = realistic door motion [OK]
Hint: Use hinge mate plus motor for rotating parts [OK]
Common Mistakes:
  • Using fixed mates that block movement
  • Confusing explode tool with motion simulation
  • Skipping rotation limits causing unrealistic motion
