      Hello,


      I have Assembly of 6 components. But i want attach the point mass to the 6 th component to replace the the first five components.By Providing mass, center of Gravity and Moment of Inertia of First five components. How to find the Center of Gravity and Moment of Inertia of first five components.

      Here is a way to do that in WB.


       


      Example: Two spheres (equal mass) with their centre of gravity (COG) at 0 mm and 4000 mm respectively. Thus their combined COG is at 2000 mm.


       


      In order to get that (2000 mm for COG), they are combined in to a multi-body part in DM (select parts, right click and choose form new part). Once we bring them in to mechanical, the information of the total assembly COG (and moment of inertia) is shown in the details of "Part". See below (it is 2000 mm as it should be).


       


      There might be of course other ways to get that info.

      No worries. Stay tuned in though because there might be some other ideas coming up later today.


       


      All the best

      what initial conditions do I have to input in Ansys explicit for it to run a rollover simulation of a bus as  specified in regulation ECE R66
