Chassis & Suspension Performance

Unified end-to-end process from requirements to simulation

A key objective of the Chassis & Suspension Performance process is: 

  1. To guarantee the structural integrity to support the vehicle body 
  2. To improve the ride and handling of the vehicle  
  3. To make sure that the vehicle can travel in the case of an abuse loading event.    

One of the key performance indicators to achieve this is the reduction of 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. The Chassis & Suspensions Performance process addresses the technical achievements to solve industry challenges for chassis and suspension from concept through production.
