预制夹芯墙板热工性能及温度应力研究

Research on Thermal Performance and Temperature Stress of Sandwich Wall Panel

为了研究市场上不同的连接件对夹芯墙板热工性能和温度应力的影响,使用abaqus有限元软件创建3个分别使用哈芬不锈钢连接件,GFRP连接件,钢筋连接件的墙体模型,以及1个作为参照的不使用连接件的复合夹芯墙体进行仿真模拟。研究结果表明使用GFRP连接件的墙体具有最好的热工性能,连接件处都产生了应力集中现象,但是均小于自身材料强度。

In order to study the influence of different reinforced polymer on the thermal performance and temperature stress of sandwich wall panels in the market.In this paper,uses ABAQUS finite element software to create three wall models using HALFEN stainless steel reinforced polymer,glass fiber reinforced plastic,steel reinforced polymer,and another wall that does not use reinforced polymer as a reference for simulation.The research results show that the wall uses glass fiber reinforced plastic has the best thermal performance and the minimum temperature stress on the connectors.All of three reinforced polymer occur stress concentration,the inner leaf wall bears greater pressure than the outer leaf wall,and the corners of the inner leaf wall are at risk of cracking.
