Analysis Of The Vibration Isolation System And Study Of The Vibration Isolator Under The Condition Of The Random Driving

As an available vibration mode, the random vibration is widely discussed in the academic and engineering field, and some achievements have been achieved in them. This thesis tries to fully study the characteristic of the vibration isolation system and its components ,so that to direct the product design and manufacture in the industry.The vibration isolation system is divided into linearity and nonlinearity. In this thesis, by pointing to the vibration isolation system in the engineering, and applying the testing method of the frequency sweep, the resonant frequency of the system is determined, and the right vibration isolator is chosen for the different installation conditions; the response solution is educed when to analog by using the method of the response solution of the determined linearity system under the random driving;the calculation method and the universal design criteria of the engineering are summarized by combining the concrete arithmetic samples and the tests.The vibration isolator has many modes as an effective vibration isolation unit. In this thesis, the discipline and performance of the vibration isolation are analyzed and studied for the non-resonance peak and the steel cable vibration isolator, and the summary is like this: even if it is under the condition of no"resonant"vibration isolation, the inherent frequency of the system is still the main factor to jam the vibration isolation's effect. The former applies to the airborne electronic equipment; and the latter applies to the large shock request and the inclement situation, such as armored airborne.There are many factors to disturb the vibration isolation system, but the flexibility of the installing base is one of the main factors. In this thesis, some useful principles for products design are all given by using the quadrille parameters'researching methods.
