OPTIMAL SHOCK AND VIBRATION PROTECTION OF A SYSTEM WITH TWO DEGREES OF FREEDOM

摘要

We examine the problem of synthesizing a technical system that protects an object against shocks and vibration. The isolation system has two degrees of freedom and consists of passive linear vibration and shock isolators. The basic data are the mass of the object, the amplitude and frequency of the vibrations, and the time dependence of the acceleration of the base during the impact. The indices (criteria) of the quality of the protection of the object are the overall dimensions of the isolation system and the maximal absolute acceleration of the object. The parameters of the isolators are calculated with impactive action of the parabolic type and harmonic vibratory action.
