abstract="The main characteristic of a gas damper (GD) is the use of gas as internal fluid, which offers an alternative to hydraulic shock absorbers. In this paper, a mathematical GD model is presented and validated. The use of a compressible fluid provides GD with a behaviour dependent on velocity, like conventional dampers, but also with a strong dependency on frequency and on stroke amplitude. This dependency allows an improvement in the traditional compromise between comfort and safety. A quarter-car model is used to evaluate the ride performance that can be expected using the GD, focusing on the cited compromise. Results are compared with the ride performance of a hydraulic shock absorber. Finally, a sensitivity study centred on the stiffness of the internal fluid is presented.<p />",
