- In the fourth chapter , the oscillation of a nonlinear beam under the axial harmonic force and the bifurcation of the weak or strongly nonlinear system have been studied
第四章讨论了一个受轴向简谐激励作用下的非线性梁的运动，运用传统的galerkin法得出时域上的动力系统，再对该系统弱、强非线性情况下的分叉进行了研究。 - Though the whole effects of the odd order and even order harmonic forces are almost destructive with each other for strong intensity , it is quiet different compared to the case of weak intensity . for weak intensity , the higher order harmonic forces can be neglected
虽然在激光强度较强时力的奇、偶高阶项的整体作用往往大部分相互抵消，但与弱场时高阶谐波项的作用可以忽略存在很大差异。 - To characterize the local discontinuity due to the crack , a rotational spring model is proposed to model the crack , on the basis , a method for crack identification is presented in this paper , which makes use of the driving - point mechanical impedance characters of the cracked beam stimulated by harmonic force
为了描述由裂纹引起的梁中波传播的不连续特性，引入弯曲弹簧模型来模拟裂纹，并在此基础上提出了利用梁结构驱动点阻抗特性的裂纹损伤识别方法。 - Under these assumptions , three kinds of excitations , namely , harmonic force with frequency equal to the structural fundamental frequency , harmonic force with frequency equal to half of the structural fundamental frequency and pulse force are inputted to the undamaged and damaged structures . then under the same excitation , the undamaged structural displacement responses , velocity responses , acceleration responses , jerk responses and responses of integrated displacement are compared with that of the damaged ones
在此假定基础上,分别将激励频率等于结构基频的简谐形激励、激励频率等于结构基频之半的简谐形激励和锤击激励输入结构,而后比较了损伤前后结构在相同激励下的位移响应、速度响应、加速度响应、加加速度响应和位移积分响应。 - Three kinds of excitations , namely , harmonic force with frequency equal to the structural fundamental frequency , harmonic force with frequency equal to half of the structural fundamental frequency and pulse force are applied to such four kinds of models . the displacement responses of the four kinds of models are calculated using sap2000 and the integrations of displacement responses are obtained by numerical calculations
将三种激励形式:激励频率等于结构基频的简谐形激励、激励频率等于结构基频之半的简谐形激励和锤击激励分别施加在这四种模型上,通过计算得到四种模型的位移响应,进而得到位移积分响应。
