Simscape piston moves without pressure difference
显示 更早的评论
Hello,
I noticed when adding a mass block to the piston rod, the pressure difference between chamber A and B seems to be zero. The piston however, moves anyway. I always assumed that there needs to be a pressure difference for the piston to move? How does simscape calculate this behavior? I added the .slx file above (ignore the error message, its from the hard stop of the actuator)

You don't need a force to keep a mass moving at constant velocity, as the acceleration is zero and F=m*a.
When I add a damper to the rod side, the mass still moves but the pressure difference is no longer zero. Give that a try :)
