Vibration simulation test machine
Vibration test simulation products during transport (Transportation), Installation (Installation) and Use (Use) environment encountered by a variety of vibration impact on the environment, this test is to simulate product in the Transportation, Installation and Use environment encountered by a variety of vibration impact on the environment, is used to determine whether the products can withstand ability of various kinds of environmental vibration.
The most commonly used vibration modes can be divided into sinusoidal vibration and random vibration.Sine vibration test method is often used in laboratory, to simulate rotation, pulsating, volatility (in ships, aircraft, vehicles, space vehicle) on the vibration and the analysis of the product structure resonance frequency and resonance point resides validation is given priority to, it is divided into frequency sweep vibration and fixed frequency vibration, its tougher depends on the frequency range, amplitude value and test duration.Random vibration is used to simulate the seismic intensity evaluation of product integrity structure and the transport environment in the packaging state, and its severity depends on the frequency range, GRMS, test duration and axial direction.
