掩护型支架全高度范围内相关构件参数变化规律的研究

STUDY OF THE LAW OF CHANGE OF THE SHIELD SUPPORT'S CORRELATIVE STRUCTURAL ELEMENT PARAMETER IN ITS FULL HEIGHT RANGES

根据在支型掩护支架的结构特点，建立了以工作高度为自变量的支架相关构件参数变化规律的数学模型，编制了相应的框图及程序，并通过实例计算得出各相关参数随高度的变化曲线。该方法及计算程序，可为支架在全高度范围内的力学分析打下基础，并为支架设计及现有支架的检测、核算提供一套快速、直观的计算方法。

Based on the structure haracters of the cholk shield support,this paper analyses the law of change of the correlatlve structuralel element parameter and pre sents a set of models which refer to the full height(H) as variable, On its basis, a corresponding computer program chart and calculation program are worked out. Taking two types of shield support as example,the correlative parameter's variable curve charts can be made.This research method and calculation program can be a basis for thedyfiamlcal analysis,and can provide a quick calculation method for the design,testing,and checking of supports.
