How does the anechoic chamber absorb sound?
Now many industrial products may have various problems in the production process, and a certain proportion of products will be unqualified after production. The abnormal sound of auto parts is a typical problem, then how do we solve the problem of abnormal sound detection of auto parts?
In the fierce competition of automotive NVH today, the noise generated by auto parts abnormal noise is not tolerated by every parts factory and main engine factory. In addition, the abnormal noise of auto parts may reflect the internal problems of components falling off.
The abnormal sound automatic detection system designed and developed by Zhongke Shengxuan is a mature equipment for the abnormal sound of auto parts. Auto abnormal noise automatic test includes an acoustic test box, a set of sound and vibration signal acquisition system, a set of real-time discriminant analysis software.
The acoustic box is mainly to provide a quiet enough test environment for product testing, to ensure that it is not affected by the external noisy workshop environment, and can carry out accurate acoustic test.
The sound and vibration signal acquisition system uses high-precision acceleration sensors and sound pressure sensors, which can collect weak abnormal sound signals from the perspective of sound and vibration.
The real-time discriminant analysis software can not only detect abnormal noise but also judge abnormal noise, such as periodic abnormal sound or sharp abnormal sound.
The operation steps of the abnormal sound detection system are as follows: put the product into the card slot; Press the start button; Take out the product under test.
The following interface is displayed:
