摘　　要：采用面切割体的方法,利用Matlab生成相应的切割曲面程序,在ANSYS中直接调用该命令生成相应的预应力曲线,加载求解。同时对摩阻损失进行了模拟,提出了解决办法,为后续预应力的模拟提供参考。The cutting method was used to simulate the prestressing force, and a curved face program was written using Matlab software. After that the program was directly called in ANSYS to build corresponding pre-stressed curve, in the end the curve was loaded to the structure and solved. Meanwhile, the simulation of the friction loss was carried on, solution was proposed. It provided reference for the following pre-stressed simulation.

关 键 词：曲线预应力 ANSYS 模拟
