TimeTooth initiated the project by mapping hard points of the suspension system. Topologically equivalent modeling was done, emulating front and rear suspension systems. Modified MacPherson strut was used as front and De Dion suspension for rear. Essential components like coil springs, dampers, jounce/rebound bumpers, joints, and bushes with appropriate stiffness and damping parameters were carefully modeled. MBD was employed to extract forces and torques applicable at various locations for subsequent detailed component-level study. Then the individual suspension system was assembled to create a comprehensive vehicle model. A simplified tire model was used to establish interaction of the suspension system with various measured road profiles. Stabilizer bar was modified to match roll stiffness. Further transmitted forces and torques experienced when vehicles navigate across diverse road profiles was analyzed. Analysis was shared with the client facilitating their team in making informed design decisions based on FEA studies.
