Multi-Post Testing

Modal suspension performance, defined.

Multimatic 4-Post Test Rig

Our multi-post rigs are developed in-house, using proprietary hardware, control systems and analytical software.

Our unique approach includes:

 

Modal evaluation – Constant peak velocity frequency sweeps conducted in heave, pitch, roll & warp from 0.25 to 40Hz.

Analysis – Proprietary software allows for modal analysis utilizing frequency response functions, summarized for efficient vehicle performance evaluation.

Roll distribution – Characterization of static and dynamic roll stiffness distribution.

Vehicle damper architecture – Provides the option for alternative damper specifications for customers to trial post-test.

Key roles of multi-post tests:

1

Providing estimates of vehicle properties.

2

Identifying sources of vehicle deficiencies.

3

Quantifying effects on suspension performance.

4

Optimizing dampers, tires and springs.

5

Characterizing different suspension systems.

6

Reviewing previous/existing vehicle set-ups.

Multimatic supports a range of vehicle development and optimization programs from dedicated multi-post facilities in Canada and the UK.
