Fatigue Vibration Ansys
Fatigue Vibration Ansys
(OP)
All,
We are desinging a frame that is to be attached to the bottom of a rail car. This frame must withstand the following acceleration criteria:
Vertical
1 ±0.2 g
5.8 x 107 cycles
Lateral
0 ±0.2 g
5.8 x 107 cycles
Longitudinal
0 ±0.2 g
1.6 x 107 cycles
What is the best way to model this in ANSYS? I'm having trouble determining whether to use random vibration, response spectrum or even transient structural.
Thanks in advance.

I too had reached the conclusion of a static anlysis of all load cases.
I may have made this post in haste.
