Hi everyone, i'm a very novice at MotionView so I apologize in advance if my questions may seem trivial. I have imported in MW a cad file (attached), my problem is: my cad file includes tires, but obviously these tires are not realistic (they are rigid bodies). I've put a jack plate to make wheels move up and down (to simulate for example a wheel that takes a hole) with the aim of estimate the force that will affect the frame. For this reason, tires cant be rigid bodies.. Is correct to use a spring dumper in order to have a better and more realistic representation of the wheel? Where to put it? Between a point, for ex the center of the wheel, and the jack plate or in place of the wheel? Ho to estimate k ad c coefficients? Or is there any other method? I think that the force on the frame, if the wheel takes a bump, won't be realistic if the wheel is simply a rigid body from a cad file: that's my problem! Thanks in advance. pulled truck.pdf
Hi Johnson, Kindly find the image sent to you in drop box Wheel with tyre assembly is given load at center by using rigid element Ground defined as shown in the image. Contact defined between tyre & Ground How this type of analysis can be done in optistruct
Hi all, How unit system is to be followed in Radioss 140. Density, Elastic modulus , force , time etc., I follwed Density in tonne/mm3, Elastic modulus in MPa, Force in N & time in ms (milli second) Output will be in MPa? What if Density in kg/m3, Elastic modulus in Pa, Force in N & time in s (second) Kindly help us in solving this propblem
