摘　　要：网状反射器天线力学分析需要设定绳索的初始张力，初始张力设定的准确性直接影响计算精度。为了快速准确地获取绳索的索力值，针对1种典型的绳索布局，通过建立数学模型，编制MATLAB程序，求解得到系统处于预平衡状态下绳索的索力值。通过ANSYS建模验证索力值求解方法的正确性，快速准确的索力值求解方法为天线模型进行力学分析奠定基础。In the process of mesh reflector antenna mechanical analysis, it is need to set the initial tension value of rope as the initial setting directly affects the precision of the calculation accuracy. If the setting is not properly, it may also lead to that the calculation is not converged. In order to obtain the, tension value of rope fast and accurately. To one typical layout of rope, the mathematics model and MATLAB program are established ：to solve the tension value of the system in the state of pre-equilibrium. ANSYS modeling is used to verify the accuracy of the method, this method make the foundation for mechanical analysis of antenna.
