Hi All,<\/p>\n
<\/p>\n
I have designed and built a set of 4 mobile lifting jacks for locomotives. Each Jack will be placed on each corner of the locomotive to lift it. The Client has ask me to do a dynamic analysis to find out if a mass hanging from on overhead crane impacting any jack would be strong enough to tip it to the ground. As the Jacks are mobile, they are not fixed to the ground. I wonder if this is possible using Explicit Dynamics. or perhaps Rigid body analysis. All examples I have found are focused on the object impacting a fixed geometry. but in my case I am concerned about the object being impacted. i.e. if I compare this with a car crashing a wall I would want to get the effects on the wall.<\/p>\n
<\/p>\n
I have read that if I am not interested in deformations, a rigid body analysis would suffice. Is this correct?<\/p>\n
<\/p>\n
Anyone cant point me to an example of something similar? or perhaps a guideline on how can I achieve this?<\/p>\n
<\/p>\n
I also want to be able to add point mass on my model. but I cannot do it in explicit dynamics. or at least in V18.1
