摘要
应用拉格朗日方程 ,得到了无阻尼弹簧测力机构在简谐激励作用下具有周期系数的运动微分方程—Mathieu方程 ;根据测力机构的不同动平衡位置 ,得到了不同形式的运动微分方程 ;根据常微分方程理论 。
The mathematical model of a undamped dynamometer subject to harmonic excitation is established by means of Lagrange equation.It is a Mathieu equation.According to the different equilibrium position of the dynamometer,the different ordinary differential equations are investigated.Using theories of ordinary differential equation and mathematical transformations,the nonresonant of the dynamometer are obtained.
