1、 Product Introduction:
The Six degree of freedom vibration table, also known as the three-axis six degree of freedom hydraulic vibration table, is a basic testing equipment that has been widely used in important engineering fields such as aerospace, aviation, water conservancy, and vehicles.
Function: Six degrees of freedom vibration, turbulence and vibration of airborne and onboard equipment.
2、 Product features:
1. Customized integrated design
2. Sine, random, impulse, waveform reproduction
3. Combination motion of different levels and degrees of freedom
4. Degree of freedom control method
5. Low friction gapless ball joint
6. Fully digital vibration control
Function introduction: The six degree of freedom vibration table is used to fully or partially simulate the vibration environment of the entire vehicle during road driving, and conduct road simulation tests on the tested products. Can reproduce sine waves, random waves, and path spectra; Simulate transportation on secondary and tertiary road surfaces; Simulate the vibration environment of a vehicle on a predetermined road surface and under predetermined form conditions, and conduct enhanced durability tests in the laboratory; Control methods such as acceleration, velocity, and displacement can be used.
3、 Test method:
1. Simulation: Implement accelerated testing on test and actual road surfaces
2. Random loading: Random excitation experiment under given self spectral density
3. Periodic test: sine excitation test, used for isolating resonance and accumulating damage (fixed frequency). Stimulating squeaks, clicks, etc
4. Durability test: including durability tests on coolers, engine mounts, seats, instrument panels, interior, etc., as well as driving comfort tests
5. Noise and vibration: used to test nonlinear vibration characteristics such as squeaking and clicking sounds of instrument panels, sunroofs, seats, etc
6. Model evaluation: Due to its multi degree of freedom, flexible and diverse force excitation functions, and sophisticated data analysis software, it can evaluate empirical models
7. Modeling: Predicting performance and optimizing designs more quickly with fewer prototypes.
