Objective To observe the changes in excitability of alpha-motoneuron responding to the muscle spindles afferent excitability in the model rats and explore whether the changes in this excitability to be changed as high frequency sinusoidal vibration acted on the soleus muscle.

The development history and present situation of oscillation technique of CCM mould are introduced, and the forms of the sine and non-sine oscillation analyzed.

Focusing on the engineering applications of multi-shaker random vibration and sine vibration tests, theoretical analysis, numerical simulation and experimental research are performed in the dissertation based on multiple-input-multiple-output (MIM.

According to the vibration issues and characteristics of aero-engines, this paper studied the engine vibration testing, controlling & vibration testing of shakers and summarized the testing concepts, contents, methods and steps of sine vibration, random vibration, and shock vibration measurement for aero-engines & th.
