Heat transer effects on vibration isolation differential pneumatic system
Original language description
The paper shows effect of heat transfer on the behaviour of vibration isolation differentical pneumatic system constructed as a mechanical system consisting of two pneumatic springs in differential configuration and connected with a throttle valve. Thissystem can be used for driver seats, ambulance couchettes, etc., and gives a possibility of tuning of whole dynamic system according to the exciting frequency. By higher displacement amplitudes the air damping comes up and its value depends mainly on thevalue of throttle valve cross-section. This value also has an effect on the natural frequency of the system. Furthermore, the heat appears by changes of the state of compressed air in both pneumatic springs. In general case the processes are not reversible and the heat is transmitted into surroundings. Dynamic properties of the system are influenced by a coefficient of heat trasfer.
