Vibration isolation is carried out, thus the dynamic and static state performance parameter of vibration isolator plays a very important role in the design process of damping noise abatement.
Existing shake table can generally be divided into mechanical, electrodynamic type, fluid pressure type according to the difference of principle and structure;By motor driving machine
It is mechanical shaker that tool mechanism, which generates the required shake table vibrated,;By fixed magnetic field and in magnetic field and it is connected with alternating current
Moving coil interaction caused by power drive shake table become electric vibration table;Vibration force is generated by fluid pressure
The shake table driven is known as hydraulic vibration gen.
Existing detection device can only individually test the dynamically or statically performance of rubber shock absorber, in vibration isolation
During the test of device and optimization design so that cost price is higher, and cannot simulate vibration isolator in practical applications
Moving situation, such as when prefabricating load, established angle, amplitude, frequency state parameter difference rubber shock absorber performance parameter.
