连杆机构被广泛应用于现代液压支架上,但是支架连杆机构的参数却至今基本上是在经验基础上用试凑法确定的。本文分析了支撑掩护式支架连杆机构的结构参数,它们之间的若干几何关系和优化目标函数和约束条件的数学模型。提出了一种被命名为“移动网格法”的优化设计新方法。建立了检验支撑掩护式支架综合特性的基本公式。用FORTRAN算法语言编写了优化设计和检验特性的两个计算程序。用本文提出的方法和程序对国产BC520—25/47型支架进行了优化设计。如果作一些适当的修正,本文对于掩护式支架的优化设计也将有用。
Connecting rod mechanism is widely used in modern hydraulic support, but the parameters of the support link mechanism has so far basically determined by trial and error method based on experience. In this paper, the structural parameters of the supporting shield type linkage mechanism, the geometric relations among them and the mathematical model for optimizing the objective function and the constraint conditions are analyzed. A new method of optimal design named “Moving Grid Method” is proposed. The basic formula to test the comprehensive characteristics of supporting shield is established. Two computational programs that optimize the design and test features are written in the FORTRAN algorithm language. The domestic BC520-25 / 47 stent was optimized by the method and procedure proposed in this paper. If you make some appropriate amendments, this article will also be useful for the optimal design of the shelves.
