A Novel Method to Suppress the Body’s Vibration Based on Time Delay for the Case of Idling

Article Preview

Abstract:

In this paper, the theory of DR (Delayed Resonator) is employed to investigate the vibration of vehicles, for the first time, and the process to suppress the vibration transmission from the engine to the body using the DR is explored. A simplified half-car model with DR is built for the case of idling, and the critical time delay is obtained by analyzing the stability of the model, additionally, the different effect of the parameters on the stable region is investigated. Method of solving the optimum values of the gain and the delay for maximum vibration suppression is built, afterwards numerical emulation is carried out to check the effect and to compare with the hydraulic engine mount. The results show that the amplitude of the body can be reduced more effectively.
