应用参数化技术开发预应力钢束设计CAD系统

Design of a Prestressed Tendon CAD System with Parametric Design Technology

论述了参数化设计技术的基本概念，对预应力钢束设计的方法进行了分析研究。在此基础上建立了钢束纵向及横向设计参数化模型，详细探讨了预应力钢束设计ＣＡＤ系统中参数化设计的实现方法。

In this paper, the basic concept of parametric design technology is described, and the design method of prestressed tendons is analyzed. Then based on the above work, parameterization models for the design of prestressed tendons in longitudinal and sectional directions are established, and the ways of accomplishment of the parametric design in the prestressed tendon CAD system are discussed in detail. Compared with traditional CAD systems, this system is more convenient for designers to express their ideas, and has higher efficiency.
