Simulate the various vibration environmental impacts encountered by the product in the transportation, installation and use environment, and determine whether the product can withstand various environmental vibrations. The most commonly used vibration methods can be divided into two types: sinusoidal vibration and random vibration. Sinusoidal vibration is a test method often used in the laboratory, which is mainly used to simulate rotation, pulsation, vibration generated by the vibration generated by ships, aircraft, vehicles, and space vehicles, as well as the resonance frequency analysis and resonance point residence verification of product structure, which is divided into two kinds of swept frequency vibration and fixed frequency vibration, and its severity depends on the frequency range, amplitude value, and test duration. Random vibrations are used to simulate the seismic strength evaluation of the overall structure of the product and the transport environment in the packaged state, depending on the frequency range, GRMS, test duration and axial direction.
