A320飞机方向舵建模

Modeling of A320 Aircraft Rudder

基于目前航空器组件的虚拟设计需求,对A320飞机方向舵提出了两种新的建模方法。一种是利用舵面点坐标数据并结合MATLAB编程及数据处理功能,拟合优化舵面轮廓曲线,将优化后的曲线导入CATIA填充获得舵面;另一种是以方向舵三视图为基础,利用CATIA的Part Design、Sketch Tracer及Generative Shape Design模块进行建模,并给出了具体步骤。所建模型可为飞机方向舵的教学及其性能分析和静力试验提供模型基础。提高教学质量和效果,培养学生的工程实践能力,同时分析虚拟模型能够提前预知可能存在的故障,及时采取相应措施,提高飞机安全性。

According to the present demand for aircraft components virtual design, two modeling methods of A320 aircraft rudder are proposed. One is to combine MATLAB programming and data processing functions with the practically measured point coordinate data of rudder face to gain and optimise the rudder contour. Then output the optimized curve to CATIA and fill it to gain rudder surface. The other is to obtain three views of rudder by referring to references. And make modeling with CATIA modules of Part Design,Sketch Tracer and Generative Shape Design. Also the process details were offered and the practical circumstances of the two methods were concluded. It will provide a model base for rudder teaching and its performance analysis and static test, improve the teaching quality and effects and develop the students＇ ability of engineering practice. At the same time possible failure of rudder can be predicted in advance with virtual modeling and thus corresponding measures can be taken in time. It will improve the aircraft safety.
