Analysis Of Structural Parameters To The Typical Cushioning System Properties And Development Of SRS Software

With the rapid development of navigation and spaceflight, such as naval ships and airplanes, carriers of power and speed have been improved greatly, the measurement accuracy of instruments is affected by the strong vibration and shock, caused by high maneuverability of carriers, especially, equipments will be destroyed by the long-term vibration and shock. Therefore, vibration isolation design and shock isolation design have a very important significance for ensuring the reliability of devices.First, in this paper, considered the environment of devices and based on the principle of vibration isolation design, methods and problems of the optimal structural parameters design of the double isolation system are analyzed, and the reasonable parameters value are presented. In order to validate them correct, the isolation system has been simulated by ANSYS. Then, based on the principle of shock isolation design, through studying on restrictor structural parameters design, methods of parameter design are given,and the system's effect with a restrictor is analyzed.At last, classic waveforms are not enough to simulate the shock environment; and domestic electrodynamic shakers do shock response spectrum (SRS) test without response of driving information, in order to solve these two problems, through studying SRS, the SRS time-history waveform synthesis method has been investigated. Using this method, a program can be made, it can get the related time-acceleration curve quickly. The calculating result indicates that the generating waveform could satisfy SRS accuracy requirement. At the same time, based daters for numerical simulation in time-domain and driving electrodynamic shakers to produce corresponding shake are provided.
