Abstract
The invention provides a server resonance weakening method which employs a high-precision dynamic signal analyzer for multi-contact measurement of vibration conditions of each part and rigid joints. Capturing vibration source positions and vibration transmission modes is the key point, and in order to guarantee reliability and precision of measured data, a vibration sensor needs to be attached to a vibration source as far as possible to capture the vibration conditions of parts in real time. Further, vibration of three positions in different directions are measured at the same time to accurately measure from multiple space angles and feed system and part vibration conditions back, so that reliability of measurement data can be guaranteed. The rotation speed of a fan is simulated and adjusted through a fan speed adjusting control panel when a server is in different power consumption, operation conditions of the fan are directly reflected by means of LED real-time display, and a system and part vibration test can be completed without electrifying the server, so that testing workload is reduced, energy conservation and environment protection are realized, and operating cost is reduced.
