 elastic line
 The length scale of the roughening is determined by an elastic line tension. Flexural strain of curvilinear tubes under the action of inertial centrifugal forces of an internal flow characterized by variable velocity and density along the elastic line is considered. The use of a precise differential equation of the rod elastic line in solving the problem of a bending flat spring provides an adequately precise evaluation of the parallelogram-point displacement coordinates. Refined approximate formulas are obtained for calculation of the coordinates of the elastic line with an error not greater than 1% of the rod length even for loads which exceed the critical Euler load by 30%. A compact algorithm is proposed for exact calculation of the coordinates of the plane elastic line of an axially compressed flexible rod under any loads. 更多

The literatures(1), (2), (3)discussed this problem in detail, but the procedures were tedious. According to the basic equation of the elastic line of double-curvature and the form of load, the author devides the problem into two groups: one is in the plane of circular bar, the other is in the perpendicular plane, each includes six first- order differential equations. By using the characteristic vector method, the funda- mental matrix solution is obtained. Because of the standard of the solution, the cal culation by means of computer is possible. 小曲率等截面圆弧杆或圆环在工程上应用甚广~([1-3]),但求解方法颇为繁琐。本文从双曲率弹性线的基本方程出发,按外载形式把圆弧杆(或圆环)的问题分解为圆弧杆平面内和垂直于圆弧杆平面两类,每类求解6个一阶微分方程组。采用特征向量法求其基本矩阵解。因此,所得到的解答具有一定的规范化,从而为进行电算创造条件。 The effects of roller profiles on contact pressure distribution have been discussed with numerical solution based on the influence coefficient method.
