I am trying to set up a motion analysis of a tire rolling over pavement to measure energy at different locations along the suspension path. To do this, I applied a simple motor to spin the wheel, and a linear motor to move the tire up and down randomly. However, I was unsure how to create a function that drives the linear motor in a random fashion between a max/min setting using the function builder.

Does Solidworks have a built in random number generator? Or is there a better way to approach this problem?

I appreaciate all the help,
