摘　　要：针对目前雷达高架结构采用ANSYS软件计算中对拉索模型简化不合理造成的计算精度低的问题,提出了基于悬链线理论的高架拉索结构分析解决方案,并编制了拉索结构分析程序,采用典型算例证明了该程序的有效性。对不同拉索垂度情况下典型的两拉索高架结构的静态变形进行了分析,并对计算结果进行了校核。结果表明,该方法可以实现考虑拉索垂度效应的索梁系统的精确分析。To solve the low accuracy problem caused by the unreasonable simplification of cable model in the ANSYS computation for radar high tower structure, the cable structure analysis solution based on catenary theory is proposed. Cable structure analysis program is given and typical instance computation verifies the effectiveness of the program. The static deformation of typical two cable high tower structure under different cable sag is analyzed , and the result is verified using ANSYS . Result shows that the method can realize accurate analysis of cable-beam structure with cable sag considered.
