摘要: 对负高斯曲面张拉膜天线罩结构刚强度进行仿真计算和实验验证。首先采用小弹性模量法进行找形分析,然后参考建筑结构荷载规范施加风载荷进行几何非线性分析计算,并根据膜结构技术规程进行刚强度校核,最后进行实物样机力学实验验证。将仿真计算结果和实验结果对比发现,加载后膜面应力最大误差为8.4%,膜面变形最大误差为5.1%,均在工程允许范围内,表明仿真计算方法的合理性。

Abstract: Structure calculation and experiment have been performed on tensioned membrane structure radome based on curved surface with negative gauss. Form-finding analysis, geometry nonlinear calculation and experiment were carried out on a physical model. After all of the work, we found the membrane stress error is 8.4% between the calculation and the experiment, and the membrane displacement error is 5.1% between the calculation and the experiment. Error band is reasonable, so we are sure that the method of calculation is accurate.

Key words: curved surface with negative gauss, tensioned membrane structure, radome, form-finding analysis, composites
