一类有正阻尼的强非线性振动问题的近似解
Approximate solutions of a class of problems of strongly nonlinear positively damped oscillation
【摘要】 用线化法,权残法和插值摄动法相结合的方法求得了一类有正阻尼的强非线性振动问题的近似瞬态解,精度好。
【Abstract】 In this paper,the approximate transient solutions of a series of problems with the strongly nonlinear positively damped oscillation were obtained by using the linearization,the weighted residual and the interpolation perturbation methods.Accuracy of this method is quite good.
