摘要
用新的改进的L P法并结合权残法求得了一般情况下 (阻尼项可以不是小量 )强非线性自激振动问题的一级近似瞬态解。近似解有很好的精度。
The first order approximate transient sotution for the strongly nonlinear excited oscillation problem in the general case (when the damped term may not be small) is obtained by using the improved L-P method integrating the method of weighted residuals (MWR). This solution has high accuracy.
