impact analysis of two bodies in block100 format

Recommended Posts

Hi,


 


I want to simulate impact between two bodies in hyperworks.


 


First body is a rectangular block which act as a cantilever beam (nodes at left side area is fixed).


 


Second body is sphere, which was initially at a certain height from the free edge of the rectangular block, is dropped on the block.


 


Modelling was done in hypermesh and there were no warning or errors.


 


But, when I plotted the displacement contour in hyperview, found that at time=0, it shows displacement for the beam (contact between the bodies actually begins at time=2 second.).


 


This gives error in the final result.


 


I have to set the displacement at time,t=0 as zero.


 


How can I do that? Please help me..

Hi Vishnu,


I guess you applied given displacement for the movement of sphere. If so the input curve for displacement must be shifted to 0. To do that you should use excel: minus each displacement value by an amount of the displacement value at t=0. Then go to HyperWorks -> XYPlots -> Curve Editor to  create the curve for given displacement.
