Twist angle of chassis

  1. Nov 30, 2012 #1
    Hi there,

    I'm a mech eng student doing a project on torsional rigidity of a space frame chassis.

    I know how to calculate the twist angle and torsional rigity at the point where the force is applied but I'm struggling to visualise and understand how I can calculate the twist angles along the length of the chassis. Normally you would take the distance between the force and pivot and the y axis displacement to get the angle, but what horizontal distance would you use at different points along the chassis? To explain better I've attached a image of the base of my chassis.

    I've marked the points where I want to get the twist angles with X's

    FYI - I'm using Abaqus to do the FEA analysis which gives me the vertical displacement values

    Thanks
