摘要: 本文提出如何使双质体碰撞振动系统在满足一定的要求下能自动隔振,提出离散系统完全稳定的概念及判别准则;并以冲击式和惯性式振动落砂机为例作了具体计算,为解决长期存在的落砂机使地基振动过烈对基础要求过高的问题提供了理论基础。

Abstract: In this paper, a theoretical analysis of automatic vibration isolation for the impacting and vibrating systems with double masses is proposed, the concept of complete stability of discrete time systems is established and a criterion for complete stability is obtained. Finally, the above results are applied to the calculation of the inertia flask shakers an may be used as the theoretical foundation to solve the long open problem of strong vibration of the base of flask shaker.
