摘要
为解决相对转动体非线性运动微分方程的计算难题,构造了一种级数解耦方法,把微分方程转化为代数方程求解,得到了相对转动体运动方程的级数解.据此可以计算工程应用中稳态相对转动体的真实转速波动.同时该法可实现测控标定仪器的转动体匀速旋转时的不均匀性测量误差分离,也为大型复杂重型旋转轴系在线实时扭振监测提供了高效算法.
For solving the difficult calculation problem of nonlinear differential equation of motion of complex revolving shaft in relative rotation , a new decoupled equation was proposed by using series method , which expands the nonlinear differential equation into a series of algebraic equations and the series solution is obtained. Based on the result of the research , the veracious speed fluctuation of revolving shaft in relative rotation in practice can be calculated for the steady state. The method also provides a technology for error detachment of measuring apparatus calibration and a highly effective algorithm for torsional vibration real-time on-line monitor of heavy-duty and complex revolving shaft .
