Hello people,
it seems to be a common issue in CAD that drawings derived from assemblies have a considerable file size. In Solidworks these drawing files sometimes take 50%-150% of the original assembly file size. Editing and saving drawings thus takes ages and is accompanied by frequent...
Thanks rb1957 for the response. I guess you are right, it would be the CG shift Δh of the entire mass, multipled by m*g. I thought it should be calculated with sort of a sum or an integral along the entire structure. For now I have taken care for the kinetic part, so yes indeed it is a...
Hi community,
I have coded an FE program in order to study the behaviour of rotating machines on an elastic structure, where I have used Timoshenko beams. Now I am calculating the total energies of the system. For the potential deformation energy U_def, it is U_def=1/2*x'*K*x, where x is the...
Hello together,
I have modelled the stiffness K, damping D and mass M matrices of a 500-D.O.F. structure in Matlab and created a state-space dynamical system (x'=Ax+Bu) from these in order to carry out simulations in the time domain. However, I notice that the highest eigenvalues of the system...
