Optimum Shock Isolation
Abstract
This report includes a discussion of the most significant achievements developed in Russia and the former Soviet Union in the theory of optimal shock isolation. Various mathematical models describing the behavior of an object mounted on a moving base which is subjected to a shock disturbance are presented. Several types of performance criteria for isolation are considered, the most important of which are the peak force transmitted to the body to be isolated and the maximum displacement of the body relative to the base. Basic problems of shock isolation are defined and the methods for solving these problems are described. Particular attention is paid to the limiting performance problem, the solution of which provides an understanding of the physical limits for the isolation efficiency. From mathematics point of view, the limiting performance problem is a special kind of open-loop optimal control problem, and the methods of optimal control, which currently are very well developed, can be applied to the limiting performance analysis. Methods for the synthesis of parameters for specific isolator configurations (feedback control laws) for shock isolators are described. The theoretical results are supported by numerous examples of solved problems for the design of optimal shock isolators. Several specific designs are presented in-depth.
