FEA development of chassis and crush structures, encompassing natural frequency (eigenvalue) analysis as well as standard torsion and beaming assessments. 58 kg semi-monocoque with welded 6061 aluminum extrusions, closed by bonded aluminum honeycomb panels of optimised core density and skin thickness. Torsional stiffness of 36,000 ft-lbs/degree, with first fundamental frequency of 116 Hz. Compliance with Lola’s rigorous packaging constraints and SR2 category’s cost-limiting material specifications while delivering easy assembly and limited tooling cost. Suspension development by Lola and Dynamic Suspensions, culminating in a class win at the 2000 24h of Le Mans by Multimatic Motorsports.
