Hi
Geesamand
FEM tools(Ansys,Nastran) are developed based on classical theory. You can check this with simple cantilever beam with concentrated load at its free end. Your results will match 99.99% with the theoretical calculations. But for the larger models FEM is a better option. Because...
Hi
dhengr,
oh sorry for that, MAT cards refers to Material cards in LS-dyna(FEA code) software from LSTC incorporation. Yes, as you rightly pointed out the coupler is fixed in center sill with a draftgear behind the coupler. I have attached the line diagram of car and coupler for ref...
Hi
I am modeling energy absorbing device for rail car (buffers/couplers). I am using LS dyna as solver(FEM). The energy absorbing device gives out reaction force of 1000 kN with displacement of 50 mm. After that the energy absorbing device collapses. The total mass of the rail-car is around 40...
Thanks a lot !!! As racookpe1978 (Nuclear) rightly indicated accn/deccn are different for car body and passengers, I have a small explanation for non consideration of passenger mass in the simulations. I request you to post your views on this.
Thanks in advance !!
If we look at the...
Hi
I am planning to excute rail crashworthiness simulation using LS dyna. I have one doubt should I consider the passenger mass for this simulation??
If anybody have worked on this, Please share your experience!!!
Thanks in advance!1
