In order to effectively study the noise of obliqueaxis plunger motor, it is necessary to accurately measure the noise of the motor. Therefore, a measurement and acquisition system for the noise level of obliqueaxis plunger motor was designed. During the test process, the obliqueaxis plunger motor was placed in the semianechoic chamber, and isolated from the loading end of the hydraulic system. So the interference of noise sources from other hydraulic components was effectively eliminated. The adjustment of the system pressure and motor speed could be completed on LabVIEW software platform, and the system pressure, flow, speed, torque and temperature parameters could be acquired online. Meanwhile, the acquisition, storage, CPB and FFT analysis and display of sound field data of obliqueaxis motor were completed in the LabShop software.The test results effectiveness was validated. The measurement and acquisition system for the noise level of obliqueaxis motor can be used to count the total amount of noise in the target frequency band, and get the corresponding frequency points of peak noise.
