Lotus Engineering Software was kind enough to send us a copy of their design software for us to use in designing our car. This software has components to design crankshafts, cams, connecting rods, suspensions and much more. The software allows the user to quickly develop a suspension system that fits their particular needs. For us we designed the suspension to have zero bump steer, roll centers that coincide front and rear and also have progressive camber rates. Of course this is not all of the design parameters, we have to keep some of it secret, but this shows the power of the software.
Here is the working environment for the software. you can click on any suspension point and move it and get real time feedback on what moving that point affects.
The software will also quickly populate graphs for any parameter that the user defines.
Camber through jounce and rebound
Bump steer, toe angle between front tires through bump
Roll Center position through bump
