摘要:
本文简介了振动对人体的不良影响以及国内外人体全身振动问题的研究现状,较详细地论述了随机激励法测量线性系统频响函数的基本原理和具体实现,编制了一个在 AppleⅡ上求系统频响函数的程序,提出了一个新的测量人体动态特性(频响函数)的方法,即利用路面的不平度引起车辆的随机振动作为激励源来测量人体的频响函数。对十二名受试者进行测试的结果表明,本文的方法是可行的,并由此法获得了我国人体动态响应的有关资料和数据。
Abstract:
In this paper,the unfavorable effects of vibration on human body and the present state of the research on whole-body vibrat.ion in the world are briefly introduced.The elemental theory and its realization of the random excitation method,by which frequency response function(FRF) of the linear system can be measured,is treated in detail.A program that can be used to find the FRF on Apple Ⅱ plus microcomputer system is developed.A new method to get human body’s frequency response function is presented.Using this method, an experiment is made on twelve voluntary subjects and its results have shown that our method is effective.From that the information about dynamic response of human body in our country is given.
