Hi. I have a SolidWorks assembly of a closed damping-type device that uses a rubber diaphragm and a highly viscous fluid inside the device. For simplicity sake, think of a bottle cap with a pod inside filled with fluid, and a rubber diaphragm stretched over the top while it has a flat base There is a fixed volume for the fluid to move within the cap walls while stretching the "pillow". I have two questions. First, is it feasible to create an animation of the device in action, from its resting state, through application and removal of a force (not an impact - just a constant force applied briefly), and its slow return to its resting state? If so, how would that be done? I could create a cylinder with a rotating rod to press the top down, but how do I mimic the movement of the diaphragm?
The second question deals with actually modelling this to adjust fluid volumes, container volume, pre-stretch of diaphragm, etc.. I have SolidWorks Flow Simulation 2010, but I don't really see any examples of how to use it to model a rubber diaphragm. I have the material properties for the rubber and the fluid, but I'm not sure this version (or any newer version) offers the capabilities I need. Can anyone point me in the right direction to show samples or people who have accomplished this? If not SolidWorks, is there another tool that can do this? Is there a shop that specializes in this kind of analysis? Thanks in advance for your assistance!
