How to measure chassis stiffness

WebCONCLUDING REMARK Finite element analysis can effectively solve the torsional stiffness analysis of chassis frame. Two method of stiffness analysis is carried out considering the wheel base of the vehicle and … Chassis stiffness is the resistance of the chassis to bending or twisting during dynamic conditions. One way to consider chassis stiffness is to observe it as a single large spring; a spring that connects the front and rear suspension systems and the left and right suspension systems.

Web1) Torsional stiffness of solid circular shaft:- For a solid circular shaft of diameter ‘d’, J = π 32 × d4 J = π 32 × d 4 Therefore torsional stiffness of the solid circular shaft is, K = GJ L = G L × [ π 32 × d4] K = G J L = G L × [ π 32 × d 4] K = Gπd4 32L K = G π d 4 32 L 2) Torsional stiffness of hollow circular shaft:- WebI would say it depends on the chassis. Since the GG chassis Impreza is relatively stiff to begin with, I'd say any effect would be near-placebo. Improvements would be in steering/cornering feel, rather than something that can be measured quantitatively, like better lap times. WebFit longer rear hubs. Be sure to measure from the hub face that meets the wheel to the chassis first (typically around 8-3/4”), so you can keep the same rear width measurement. Fit seat struts (maximum of 4 total).
