液靜壓系統之動態參數鑑別

Identification of Hydrostatic System with the Membrane Restrictor

摘要


液靜壓系統動態特性會隨著不同節流器結構、流量、壓力等特性而改變。本文鑑別液靜壓系統動態特性C、K參數,通常系統的質量為常數。而阻尼C與剛性K常隨時間與位移改變,為系統重要的動態參數。本文首先求得系統的暫態響應,再利用曲線擬合方式鑑別系統動態參數K與C之值。

The hydrostatic dynamic characteristics will change with different restrictors of structure, flow rate and pressure. In this paper the hydrostatic system parameters M (system mass), C (coefficient of viscous damping) and K ((coefficient of stiffness) are identified. In general the system mass is constant, but C and K will be changed with time and displacement. Firstly, the transient response of the system is obtained. Then using curve fitting we identify the hydrostatic bearing dynamic parameters C and K.
