摘要

The testing principles of dynamic characteristics of eletrohydraulic servo valve are expounded completely in time and frequency domains. The high frequency noise in the testing process is eliminated by use of the wavelet transform-based noise suppression method. The dynamic characteristics of a servo valve are tested on the VICAT system for characteristic testing of servo valve. The characteristic curves before and after the wavelet transform-based noise suppression are given.
