支承点位移对点支式玻璃板承载性能的影响
|
摘要
采用有限元软件ANSYS建立了点支式玻璃板的计算模型,应用线弹性有限元方法分析了几种较不利的支承点位移分别对四点及六点支承玻璃板孔边应力、跨中应力、跨中挠度等承载性能的影响。结果表明:支承点位移对以边中点应力作为控制应力的四点支承玻璃板承载性能的影响很小,而对以孔边应力作为控制应力的六点支承玻璃板承载性能的影响较大。
The calculated models of point-supported glass panels were built by using finite element software ANSYS.The influences of supporting point displacement on the load-carrying properties of four and six point-supported glass panels,such as hole-edge stress,middle-span stress and middle-span deflection were analyzed by means of linear elastic finite element method.The results illustrate that supporting point displacement has little influence on the load-carrying properties of four point-supported glass panels which is controlled by the stress of central point of edges,but has relatively great influence on the load-carrying properties of six point-supported glass panels with the determinant stress of points around holes.
