Damper with optimised progressive damping characteristic is better at shock mitigation than suspended commercial seat as presently available

A single degree-of-freedom simulation model of a seat equipped with a non-linear fore-and-aft suspension system was developed. The performance of a typical fore-and-aft suspension system was analysed using typical vibration and shock acceleration signals measured in loaders while travelling on off-road terrain and while driving the bucket into a heap of soil. The simulations are of use to seat manufacturers in developing improved fore-and-aft seat suspension for wheel loaders.
