Vertical Vibration Reliability Test
Through the vibration controller of the signal source output to the power amplifier, amplified by the signal and then input to the vibration table body, generating excitation source, simulate the actual situation of the specimen to the vertical vibration test; through the acceleration sensor signal acquisition and input to Vibration control device, the output signal and feedback signal stacking calculation, to achieve the excitation source and the target spectrum of high degree of coincidence. The system is given by the signal target spectrum, to complete the vibration test of the specimen, the test specimen vibration durability, integrity and so on.
Random vibration test
Random vibration test according to the actual environmental requirements are the following types: broadband random vibration test, narrowband random vibration test, broadband random plus one or several sinusoidal signals, broadband random plus one or several narrowband random. The first two are randomized trials, the latter two are mixed type can also be classified into randomized trials. Stochastic control uses the transfer function equalization method to continuously output Gaussian random signals, and quickly performs real-time accurate closed-loop control. The built-in adaptive control algorithm can react quickly to the nonlinearity of the system. The random control also provides kurtosis control functions specifically designed for reliability enhancement tests. The working principle of the electric shaking table is based on the amperometric law of the current-carrying conductor acting in the magnetic field by the electromagnetic force
