What is mainly discussed in this dissertation is as follows : the fault mechanism and vibration frequency feature of hydroelectric vibration are analyzed, induced and reorganized. the select and placement of detecting positions of parameters such as vibration, swing and pressure pulsation are researched, and the corresponding sensors are selected to monitor
Thrust fluctuation ratio
In addition, a calculating method of parametrically designing hydraulic motor with non - circular planetary gear is proposed aiming at maximal unit displacement and the minimal pulsation ratio by means of visual c + + 6. 0 software
Secondly, based on the research of flow characteristic of hydraulic motor with multi cylindrical gear, optimal conditions of tooth number are got to minimal the pulsation ratio of motor in the design of hydraulic motor
Then a formula about flow of the gear pump and the coefficient of engagement overlap to find is obtained by area method. through analysis contact ratio and overlap ratio has the effect on the volume oil and the flow pulsating ratio
