Shock Response Analysis Method And Its Application

Shock Response Spectrum (SRS) analysis is one of the best important methods of shock response test and has been fully developed and broadly applied. There are many researches about SRS method and the results of these researches have been broadly applied into products shock resistance design and shock environment simulative test. In recent years, using shaker system to execute SRS test has been the main method in technical engineering with the development of computer science and digital control system. The amalgamation of SRS technique and real-time signal analysis technique gives birth to advanced shock test real-time control system and this system replaces quickly the common method and technique. Now there have been many high performance shaker system and its' corresponding real-time control system which makes good test results.In this paper, the main contents are the following:Chapter 1 describes the development of shock test technique and main research background of SRS, and analyses the contents, difficulty and creation of this paper.Chapter 2 studies the theory, physical models, and general algorisms of SRS, and gives a evaluation about SRS technique.Chapter 3 makes researches about SRS digital application methods. Impulse Invariant Filter method and Ramp Invariant Filter method are studied through continuous system simulation, and their performance and improvement are also discussed.Chapter 4 studies the SRS synthesis and analyzes its method, progress and principle. Practical SRS synthesis is realized using WAVSYN.Chapter 5 analyses the structure and function of shock test real-time control system and digital control test system; the high speed and real-time performance of shock test real-time control system based on DSP chips are studied.Chapter 6 gives a conclusion of this paper and analyses the future research of SRS field.
