航空轮胎成品材料分布图计算机辅助设计 航空轮胎成品材料分布图计算机辅助设计 摘要 计算机辅助设计在普通轮胎设计中得到了广泛的应用，由于航空轮胎在使 用性能、结构特征上不同于车辆轮胎，航空轮胎的计算机辅助设计进展较慢， 特别是在航空轮胎成品材料分布图的绘制上，国内航空轮胎设计一直采用手工 计算机绘图的方法绘制成品航空轮胎的材料分布图。 本论文提出了采用在AutoCAD绘图软件的基础上，利用VisualLISP集成开 发环境，运用AutoLISP语言及DCL语言实现了航空轮胎双钢圈442及332型胎 圈包边结构型式成品材料分布图的绘制。软件没有按照一些通用轮胎材料分布 图软件采用在程序界面输入参数，而后自动绘制轮胎完成轮胎的成品材料分布 图的方式。而是采用在绘制过程中每一步通过设计者与软件交互进行输入合适 参数进行设计的方式，对于航空轮胎这种结构尺寸没有规律的成品材料分布图 来讲是非常合适的，给了设计人员很大的自主性。 研发完成后的软件，结合了航空轮胎设计的特点，包括可视化的参数输入 界面以及人机交互的航空轮胎成品材料分布图绘制过程，使用非常方便。通过 软件的使用使航空轮胎成品材料分布图的绘制周期大大缩短。 关键词：航空轮胎计算机辅助设计材料分布图AutoCAD VisualLISP MATERIAL MATERIAL DISTRlBUTl0N DRAWlNG’S COMPUTER AIDED DESlGN FOR AIRCARFT TlRE OF FINlSHED PRODUCT ABSTRACT Computer aided design(CAD)has got the extensive application in tire design．however，its development in aircraft tire design has not made much progress aS the characteristics of aircraft tire are quite different from that of ground vehicle tires．Especially material distribution drawing in the aviation tire finished product，the designer of the aviation tire in domestic has been drawing material distribution drawing by hands in computer． In thi S paper，the author put forward on the foundation of the AutoCAD，made full use of the integration development environment of the VisualLISP，AutOLISP language and DCL language，developed a soft of CAD in aircraft tire design．The soft can draw material distribution drawing of aircraft tire for two wire beads，including 4-4—2 and 3-3—2 ply turnups structure． The software’S structure is different from the general CAD of t ire． the parameter of the aircraft tire can be import from the interface of the soft．The each procedure drawing of material distribution drawing must import parameter of designer through man-machine conversation．The way of drawing material distribution drawing is very fit for the aircraft tire’S material distribution drawing，the designer can play important 1 role role in the procedure．It showed the characteristic of the aircraft tire- Compare with drawing of handiwork，
