摘要
通过使用二维弹性接触有限元程序对多级隔板进行计算分析,就目前隔板试验中存在问题进行了探讨。分析了(1)试验时的集中载荷与工作状态下的均布载荷造成的挠度差异;(2)试验时载荷的不均匀造成的差异;(3)加载支点数的影响;(4)加载位置影响;(5)支承刚度影响。
This paper calculates and analyzes many stages of diaphragm using 2D elastic contacting finite-element programme, and discusses the following problems existing in present diaphragm test:(l)the deflection difference between integrating load in test condition and distributing load in working condition; (2)the deflection difference caused by load inequality when testing; (3)effect of loading point number; (4)effect of loading position; (5)effect of supporting stiffness.
