    How to make a simple flex simulation of a go kart rigid axle?

    Adam Fink

      Hi,

       

      As a starter project (SW2010), I am trying to make a crude simulation of a Go Kart rear axle flex when using a combination of 3 bearing supports (see pic below).

      For that matter I use the "bearing" fixtures and apply a force at the extremities of my axle

      Should be quite simple, yet I keep getting  the " model is unstable..." error when using "direct sparse" solver  or "status code 9 : matrix singular.."  when using the "FFEplus"solver

      I must be missing something very obvious. Could someone shade a light on this or suggest  a relevent reference document/video tutorial for axle/bearing simulationst?

       

      Thanks in advance for your help,
