Abstract

This paper mainly studies the acoustic optimization design based on typical valve-controlled hydraulic system. Firstly, by changing the output pressure and other key parameters, the pipeline pressure curve of the pump, valve group, hydraulic cylinder and other key equipment is calculated, and its noise characteristics are analyzed. Secondly, the accumulator, throttle valve and other typical vibration damping components are added to the system to simulate the influence of typical vibration damping components on the system noise under different parameters. In addition, this paper also studies the influence of pipeline parameters on the noise of the hydraulic system, and obtains the influence of different pipeline parameters on the pressure pulsation of the system by setting different pipe clamp distances and other influences on the natural frequency of the system. In order to complete the above analysis process, this paper first builds simulation models of hydraulic oil source and typical hydraulic system by AMESim. Then by using the control variable method , various working conditions are calculated. According to the simulation results, the noise characteristics and the acoustic design principles of the typical hydraulic system are summarized in this paper.
