In this paper, a direct integration method used to solving non-linear structural dynamic differential equations, in which the acceleration is appr- oximated by second order polynomial of time interval is proposed. This method is unconditional stable no matter whether the physical damp- ing of the structure system is large or small so long as it exists. It possess third order accuracy and better arithmetic damping property. The effects of decay in amplitude and extension in period are remarkable on higher mode and very little on lower mode. Moreover, there is also no "over shoot", phe- nomenon in this method. In solving n degree of freedom structual dynamic problems by this method, when either the step length of time, structure rigidity or damping is changed, it needs to solve 2n×2n algebrac linar equations in one step. If all the step length of time, structure rigidity and damping are not changed, it needs only to complete the back substitution solving procedure in Gauss elimina- tion. This method has remarkable better properties than all other direct inte- gration methods existed.

Wilson 's θ-method is well known and is effectively used in the domain of structural dynamic analysis. An improvement is made in this paper in order to get more accurate results and to accelerate the convergence of the dynamic equations. The main idea is that the acceleration should be approximated in the time interval by a quadratic form:The accuracy is raised to O(Δt3 ) instead of O(Δt2 ) in the Wilson's method.The stability of the method is unconditional. In the sense that the physical damping of the structure...

Wilson 's θ-method is well known and is effectively used in the domain of structural dynamic analysis. An improvement is made in this paper in order to get more accurate results and to accelerate the convergence of the dynamic equations. The main idea is that the acceleration should be approximated in the time interval by a quadratic form:The accuracy is raised to O(Δt3 ) instead of O(Δt2 ) in the Wilson's method.The stability of the method is unconditional. In the sense that the physical damping of the structure system can either large or small so long as it exists. It has an accuracy of third order and a better arithmetic damping property. The effects of decay in amplitude and extension in period are remarkable on higher modes and very little on lower modes. Moreover, there is also no ' over shooting ' phenomenon in this method.In solving n degree of freedom structural dynamic problems by this method, when the step length of time, the structural rigidity or the damping is changed, it needs to solve 2n × 2n algebraic linear equations in each step. If all the step length of time, the structural rigidity and damping are not changed, it needs only to accomplish the back substitution solving procedure in Gauss elimination. This method has remarkable better properties than all other direct integration method.In the end of this paper numerical examples which are used to compare with other method are given.

本文给出综合评判的一个数学模型。设 X 是有限对象集,U 是有限判据集,|U|=m,R 是 X×U 上的模糊关系,三元组(X,U,R)称为评判空间。评判函数 f:[0,1]~m→R 应满足正则性、递增性和连续性等条件,借助评判函数可对 X 中的对象排序。我们证明了:在一定的附加条件下,评判函数f(z_1,……,z_m)可分别表为 sum from i=1 to m a_iz_i,(a_i)和。最后提出一个二级评判的方法。
