摘要
建立了一种普遍的解析理论 ,利用简正模态法研究确定性位移激励下拉扭耦合螺旋形弹簧的动力响应。假定位移激励是谐波变化的 ,得到了各种谐波位移激励下封闭形式的解。
A general analytical theory is developed. The dynamic response of coupled tensional torsional helical spring under deterministic displacement excitation is investigated by using normal mode method. The displacement excitation is assumed to be harmonic varying. The closed form solutions are obtained under various harmonic displacement excitations. The numerical results of dynamic extensional displacement and torsional displacement are presented and discussed.
