    Simulating Chassis with Point Force?

    Chen Ying

      Hello everyone,

       

      I am trying to simulate a rollover situation with a chassis I have designed. In the picture below, I am applying a 5g load on the front roll cage (circled in red). However when I select body to apply the force on, it applies it along the entire length of the the front roll cage (shown in second picture)

      I have tried using the split lines feature near the top of the roll cage and had the forces act on points created from the split line. However I got some strange results (min FOS = 0.44, see below) even though the tube geometry (1.50 OD x 0.125 Wall) and material (aluminum 6061) should realisitically indicate it will not fail. Any help? (file is attached)
