Abstract

The invention relates to a motor NVH (noise, vibration and harshness) testing system and method based on LabView. The system comprises an industrial control computer with LabVIEW, a data acquisition unit, a sensor and a programmable power supply, wherein the sensor comprises an acceleration sensor, a rotating speed sensor and a noise sensor; the industrial control computer with the LabVIEW is connected with a motor to be detected through the programmable power supply; the acceleration sensor, the rotating speed sensor and the noise sensor are respectively connected with the motor to be detected; and the industrial control computer is respectively connected with the acceleration sensor, the rotating speed sensor and the noise sensor through the data acquisition unit. Compared with the priorart, the motor NVH testing system and method based on LabView has the advantages of low implementation cost, high reliability, high production efficiency and the like.

Description

technical field [0001] The invention relates to a motor NVH test system, in particular to a LabView-based motor NVH (Noise, Vibration, Harshness, noise, vibration and harshness) test system and method. Background technique [0002] With the continuous improvement of people's living standards, noise has gradually attracted people's attention. NVH technology plays an important role in modern industry. By analyzing the mechanism of NVH technology in motors, we will summarize and solve the vibration and noise problems of motors. That is NVH technology. And it is decomposed into the development and design process of each component of the motor, which has certain practical significance for the development and design process of motor components against NVH. [0003] At present, the NVH analysis of motors requires professional equipment for detection, which is expensive and the detection cost is too high. Contents of the invention [0004] The purpose of the present invention is...
