Success Story Minimising Mass and Increasing Durability of a Vehicle Suspension System Using HyperStudy & OptiStruct Rear Twist Beam (RTB) Suspension systems are commonly used in A, B and increasingly C class vehicles due to their low manufacturing cost, small package requirement and the acceptable vehicle handling performance they produce. RTB Design is a complex challenge which requires careful consideration of elastokinematic performance in addition to meeting stiffness and durability targets. Design of Experiments (DOE) and optimisation methods are being used to explore the available design space and minimise the mass of a low cost RTB design.
