Vibration test

Project Introduction

Vibration test is to simulate the various vibration environmental impacts encountered by the product in the transportation, installation and use environment. This test is to simulate the various vibration environmental impacts encountered by the product in the transportation, installation and use environment. This kind of vibration environmental impact is used to 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 laboratories to simulate vibrations generated by rotation, pulsation, shock (appearing on ships, airplanes, vehicles, and space vehicles), as well as product structure resonance frequency analysis and resonance point stay verification Mainly, it is divided into swept frequency vibration and fixed frequency vibration. Its severity depends on the frequency range, amplitude value, and test duration. Random vibration is used to simulate the overall structure of the product to evaluate the seismic strength and the shipping environment in the packaged state. Its severity depends on the frequency range, GRMS, test duration and axial direction.
