Evaluation of a Driver’s Seat’s Dynamic Properties

Abstract

Summary. 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.

Novel Design of Variable Stiffness Pneumatic Flexible Shaft Coupling: Determining the Mathematical-Physical Model and Potential Benefits

“…However, variable stiffness and semi-active vibroisolation are developed not only for elements with torsional loads but also for suspension of rectilinearly oscillating masses in driver's seats [53,54], base mounts of industrial machinery [55], and vehicles [56].…”

Measurement of Air Springs Volume Using Indirect Method in the Design of Selected Pneumatic Devices

“…The new mobile device is equipped with a special compressed air distribution system, which important components are air springs. Air springs have wide range of use (Kohl and Pešík, 2016;Pešík and Němeček, 1997;Sturm and Pešík, 2017). In this case, the air springs are modified and used as air pressure tanks with various functions in the mobile device.…”
