Description

technical field [0001] The invention relates to vibration test and vibration signal detection technology. Background technique [0002] Mechanical faults often have different interpretations in different literature or in different application environments, but generally speaking, mechanical faults are identified as abnormal working conditions of equipment, and mechanical faults can affect mechanical performance to varying degrees according to their fault degrees. Normal operation or even damage, and mechanical failure is inevitable during the operation of the equipment. Therefore, the mechanical failure needs real-time monitoring and simulation, and the different signs of the various stages of the mechanical failure can be found in time, so as to block the further expansion of the mechanical failure in time and prevent cause more damage. [0003] Since mechanical faults can be simulated, in addition to real-time monitoring during equipment operation, simulation experiments ...
