摘要
从辛几何的观点出发,得到了四阶杆振动方程的多级辛算法,此算法具有较好的稳定性,数值例子表明辛算法具有良好的长时间的数值稳定。
Author constructed some mutil - stages symplectic schemes for four - order rob vibration equation from the viewpoint of symplectic geometry. These schemes have excellent stability. It shows that these schemes are stable during a long time by an example.
