The synthesis of under-damping vibrations with the same frequency at two mutual vertical directions is studied and investigated using Model JGYW-2 double-single vibration apparatus.
The utility model relates to a mechanical press damping shock absorbing apparatus, which is used for controlling the noise caused by the impact vibration of the mechanical press.
