Ok Got it.
\nThanks again Erik.
\nTo add to the discussion the above panel is designed to be mounted in a locomotive. Now a days we came across analysis of products related to defense as well. In which customer specifications provide us the value of shock in terms of Gs and its curve behavior along with the time. Like 57 Gs for 35 mili second full sine wave. Those structures are supported from the bottom as well as from top through the commercially available shock mounts. As per the results provided by our analysis team, our structures demands lot of support members to mitigate the generated stresses and to be within the yielding zone.
\nHowever I talked to other manufacturers also but their structure are pretty light weight as compared to ours for the same shock amount and period. I don’t understand how but I want to know the correct methodology like selection of time step (solved as above), effect of shock mounts, weather base excitation to be considered or apply acceleration on all bodies, like such other factors which I may not know or our team may be missing to consider for the analysis and we are getting some incorrect results.
\nI request if you have any solve example of such a problem, please share as that will be a very great help for me.<\/p>\n","protected":false},"template":"","class_list":["post-187900","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
