Evaluation of a driver’s seat’s dynamic properties

The springing support in a driver’s seat is a very serious issue, such that manufacturers are increasing their efforts to optimize the dynamic properties of this kind of seat. The main optimization criterion is vibration insulation efficiency with regard to health research and associated health standards and regulations. This article deals with the definition of the optimal driver’s seat properties in relation to two examples of springing systems with different kinds of damping. The first case involves the springing support of a driver’s seat that uses a pneumatic spring and a telescopic hydraulic damper. In the second case, the damping effect is achieved by two pneumatic springs whose forces effect a phase shift due to a throttle valve located in the connecting piping system.
