摘　　要：槽式太阳能TTC桁架结构进行数值建模和有限元分析时存在许多问题,比如耗时长、工作量大、操作技术水平要求高以及模型参数繁多不易更改等。为了解决这些问题,采用ANSYS二次开发工具APDL对TTC桁架结构进行参数化建模,并结合Visual C++语言对其进行编程,创建人性化的参数化建模与数值分析软件系统。系统提取了模型中的主要结构参数作为主参数,并与其它次要参数建立了相应的算法关系。同时建立了对模型的基本参数、边界条件、载荷以及网格尺寸大小等进行控制的方法和算法。实现了在多工况条件下对复杂工作环境的快速简便的有限元建模和数值模拟,大大减少了模型建模时的工作量,提高了数值建模计算工作效率。During the numerical modeling and FE(Finite Element)analysis of slot type solar energy TTC truss structure,there are some problems such as time consuming,heavy workloads,high level requirement of operation skill and difficulty to change the parameters of various model etcetera.In order to solve the problems,the use of secondary development tool APDL of ANSYS software to parametric modeling for the TTC truss structure,and combination with the Visual C++programming,develops the parametric modeling and numerical analysis software system.The main structure parameters of the model are extracted as the main parameters by the system,and the corresponding algorithm is established with the other secondary parameters.At the same time,the methods and algorithms of basic parameters,boundary conditions,loads and mesh sizes of the model for control are established.The fast and easy FE modeling and numerical simulation of complex working environment are realized under the multi working conditions,which is greatly reduced the workload of modeling and improves the efficiency of numerical modeling and computing.
