A Research on the Method for Simplifying Dynamic Envelope of Engine Based on CATIA/CAA

针对在CATIA中使用传统方法生成发动机包络时效率低下的情况,提出了一种简化发动机动态包络模型的方法。该方法基于CAA,以CATIA为平台,Visual C++为编程工具,快速自动生成发动机多工况下的动态包络。这种简化方法缩短了计算机运行时间,提高了工作效率,为发动机动态干涉校验提供了坚实的基础。

In method for simplifying view of the low efficiency in creating engine envelope with conventional method in CATIA, a the dynamic envelope model of engine is proposed. Based on CAA, with CATIA as platform and Visual C ＋ ＋ as programming tool, the method can quickly and automatically create the dynamic envelope of engine under multi-working conditions. The simplification method can shorten the running time of computer, enhance work efficiency, providing a solid base for the dynamic interference checking of engine.
