【 摘 要 】

This study presents a technique to estimate the parameter values of the soft switch, which can be used for reduction of pressure surge due to abrupt mode shift or speed reversal in high pressure hydrostatic transmission. The estimation of critical parameters is essential for component design and fabrication thereafter. Different hydraulic systems should have different parameter values of the soft switch. It depends on the developed pressure in the switched volume and valve transition time. The throttling energy loss of an on/off valve controlled hydraulic system is influenced by different component parameters of the soft switch, which has also been investigated in this work.
