KRD50 Transportation Simulation Vibration Testing Machine

Name: KRD50 Transportation Simulation Vibration Testing Machine
Brand: CME Technology Co., Ltd.

KRD50 transportation simulation vibration testing machine can replace the actual running automotive test to complete the road transportation simulation test of packaged or unpackaged products in the laboratory. The simulation conditions are as follows: the random vibration environment generated when the vehicle speed is 20~80km/h on the intermediate surface of 3nd or 4th highway. It is applied to evaluate the adaptability of the product to withstand the vibration of automobile transportation under packaged or non-packaged condition and to evaluate its structural integrity.

FEATURES OF KRD50 TRANSPORTATION SIMULATION VIBRATION TESTING MACHINE

Adopt a mechanical random vibration simulator, and adjust the system's natural frequency, excitation frequency, and vibration amplitude to make the test table meet the technical index requirements
Simple and reliable structure, the operation is convenient. It is especially suitable for transportation tests on large-scale and large-mass products
Adopt combined spring suspension, which can achieve a vibration isolation effect without a special foundation
Vehicle transportation vibration is broadband random vibration, and the instantaneous value of vibration basically meets the normal distribution
The simulation of broadband random vibration is used a subband approach, each subband contains a main natural frequency and meets the power spectrum of the subband
Adopt truck chassis suspension technology, the acceleration factor can be adjusted
