摘要
提出了一种求解非线性动力学方程的预测-校正数值算法.由于校正过程消除了线性化带来的误差,使计算精度得到较大提高.数值算例表明该方法正确、有效.
A new numerical integration scheme incorporating a predict-correct algorithm for solving the nonlinear dynamic systems was proposed in this paper. Since the error caused by linearization can be eliminated in the correction process, the calculation accuracy is greatly improved. Numericl results show the correctness and validity of the method.
