VSB14 Suspension Assessment

We use various analysis methods including FEA and MBD to simulate stresses on a suspension system to VSB14 and other client requirements. Whether it’s fabricated suspension arms, custom uprights or modifications to OEM components, these methods can be used to assess structural integrity and identify any areas of concern.

Springs, bumpstops and even flexible bushes can be modelled to achieve a high degree of accuracy. Various bump, cornering and braking forces are applied at the tyre contact patch to calculate stress levels within each component and ensure that they will withstand the loads specified in VSB14.

The suspension kinematics can also be assessed using MBD, by moving the suspension through its full range of steering travel and vertical wheel travel to see how camber and toe settings changed throughout the range of motion. We make sure that these values remain within acceptable ranges and show smooth rates of change, minimised bump steer and roll steer, all of which will help contribute to neutral and predictable handling characteristics for a vehicle.

Using simulation allows us to perform a thorough assessment of the suspension system without destroying any components, as would potentially be the case if physical testing was used.
