摘要
对精细辛几何算法设计了高效的迭代过程,减少了精细积分的计算量,同时提出了精细辛算法的简化形式,避免了复杂的矩阵求逆运算,并给出了相应的误差估计,最后编制了程序进行验证,证明了所采取的方法能够使计算快捷,精度高,稳定性好.
In this paper an efficient iteration format of the precise symplectic integration method is proposed to reduce the computation amount. At the same time, the simplified form and its error estimation are also proposed to avoid complicated matrix inversion operation. This method is programmed to justify its validity. It is proved that this method can speed up the calculation process and has high precision and stability.
