Greetings!
This post is in continuation with our previous post about 'Design of Suspension and Steering System for a Formula Student Car (FSAE) using 3DEXPERIENCE Platform'. This post will be explaining about the process and obtained results for camber change rate in case of roll in CATIA DBM.
For this, VeSyMa suspension library from CATIA DBM is used for carrying out the iterations. A template named “Front MacPherson Half Car Roll” from VeSyMa Suspension library is used for iterating geometry. In this template, the “MacPherson Suspension” block is replaced by “Double Wishbone” block using change class command available in the CATIA DBM.
By providing the input parameters related to the suspension geometry, Camber at ±3° roll is checked.

The value of camber was computed at ±3° roll for different values of roll centre. The optimum value of the camber was obtained at 82 mm roll centre above the ground. For the optimum geometry, the camber in -3° on left and right wheel is +2.96 and -3.01 degrees respectively, and the camber in +3° roll on left and right wheel is -3.01 and +2.96 degrees respectively.
Furthermore, after the completion of the suspension geometry, selection and calculation for damper and spring will be carried out.
