I am trying to model a distributed load for Nastran analysis. The shape is a hollow cylinder covered with rubber from inside. I have no idea about the rubber stiffness properties and thats why I ingore the rubber part and would like to use RBE2, RBE3 or some other element to simulate the force...
If I have the inertia, inertia axis and mass properties of an engine, how can I calculate the roll axis when a torque in some direcion (which I have the data for) is applied ?
I am trying to determine the first couple of frequencies of a drive shaft. It consists of three seperate pieces connected with elastic couplings. It is attached to the vehicle, so that the boundary conditions as in real life. How can I do the test?
for example, could I do a hammer test and get...
hi,
I am trying to calculate the shake, inertial and moment force acting on the crankshaft. The reciprocating motion of the piston+pin+small end of the conrod creates these forces. Still I need the right formula to figure out the correct numbers. Also, if these are for a 4 cylinder engine, do I...
