摘要
Abstract
The vibration and noise of the bent-axis axial piston motor is investigated by a combination of test and simulation.Firstly,the vibration and noise excitation sources of piston motor are investigated and analyzed according to its structural composition and working principle.Secondly,the modal analysis and harmonic response analysis and calculations are carried out by using the simulation software to get the intrinsic frequency of the piston motor and the frequency curves of vibration-related parameters,and the accuracy of the simulation model and test method is verified with vibration tests.Finally,the noise radiation analysis and simulation of the piston motor is carried out by acoustic-vibration coupling method,and the reasonableness of the simulation results is verified with noise test.It is concluded that the peak frequencies of vibration and noise tests are around 700 Hz,which is highly consistent with the theoretical value of excitation frequency 700 Hz,and also close to the first-order intrinsic frequency 704 Hz of the piston motor shell.It proves that the piston motor system is in resonance at this frequency,and proposes optimization directions for vibration reduction and noise reduction of piston motor structure.This study reveals the main mechanism of the vibration noise of the piston motor and provides a basis for its vibration reduction and noise reduction.关键词
