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.

Then the paper used the projection operator to structure the normal coordinate component,thus combined 15 normal vibration patterns of propadiene molecule.

Based on the theory of the particles suspended in fluid experience acoustic radiation forces and the structure model of one-dimensional multilayer resonance separator,the structure model based on the two-dimensional normal vibration modes was proposed.

Implementation of an algorithm for MIMO sinusoidal vibration test control system;
