To start my analysis, I’m going to switch to Motion Analysis by selecting it in the pulldown that says Animation. Make sure SOLIDWORKS Motion is turned on in your Add-ins. You can use that, but I’ll create a new one by right clicking and selecting Create New Motion Study.

Crankshaft assemblyĪt the bottom of the graphics area is a default Motion Study 1 that is in every part and assembly. I’ll guess at the RPM value to see what velocity I get at the ends of the pistons. I need to know the RPM on my motor to make sure the pistons have the correct velocity while the crankshaft is spinning. I can rotate the crankshaft to test the motion by moving it. I have all of the parts I need and I’ve put in mates. Let’s take a look at this drive assembly that I’m using in my RC car. Third, the motion will take the mates in your assembly into account, so make sure those are set up correctly. Second, in order for the results to be accurate, you must have density assigned to all the components in the analysis. First, all of the bodies need to be rigid. We have a video on our YouTube channel about setting this type of study up here.īefore we get started, there are some important assumptions that you need to make. If you don’t know the timing of events in your study, then you need event-based motion. Motion can simulate moving or dynamic systems and will give outputs to size your design. Motion analysis is a powerful tool that’s available if you have SOLIDWORKS Premium or Simulation Standard, Professional and Premium. Thanks for stopping by! The goal of this article is to give you an overview of time-based motion analysis.
