CHASSIS AND SUSPENSION STRENGTH & DURABILITY

A state-of-the-art simulation solution for the complete design of the chassis and suspension from at the concept stage to at the final stage

Key objectives of chassis and suspension strength & durability are 1) to guarantee the structural integrity of the vehicle chassis and suspension for supporting the vehicle body, 2) to improve the ride and handling of the vehicle and 3) to make sure that the vehicle meets all the regulation and quality requirements. One of the key performance indicators to achieve this is to reduce the suspension unsprung mass while maintaining its stiffness and strength. Reducing unsprung mass helps improve the steering and handling of the vehicle by allowing the car to react quicker to bumps and imperfections on the road by maintaining grip.

Each of the components of the chassis and suspension have unique requirements to ensure they work correctly under regular service loads as well as minimize damage during abuse cases. There are several techniques used to minimize weight such as topology optimization, material selection and enhancement of controls. Electric vehicles have their own unique requirements and are typically heavier than internal combustion engine vehicles. Precise estimates or measurements of the loads and the response are essential to optimize the components. Chassis and suspension strength & durability addresses the technical achievements to solve industry challenges from concept through production. Vehicle manufacturers can realize significant cost savings by reducing time to market and eliminating late-phase design changes. Improving the performance and durability through virtual simulation will significantly reduce warranty costs.
