Polynomial approximation method of canopy track for powered supports 液压支架梁端轨迹的多项式逼近方法
By orthogonal polynomial approximation method , we first reduce the random system into its deterministic equivalent one , so the response problem of a random system can be transformed into that of a deterministic system 有关上述gegenbauer多项式方法在随机振动问题中的应用,现有文献中尚未见报道。上述三种方法都可以用于求解随机结构的演变随机均方响应问题。
