中文摘要: 针对计算开环控制的胎面缠绕生产系统中配置的胎面缠绕系统算法性能差的问题, 本文提出了一种基于NURBS曲线的胎面缠绕仿真算法并进行了实例验证. 目前轮胎胎面缠绕开环控制系统配置的胎面缠绕仿真软件多使用直线与圆弧对缠绕过程中的曲线进行仿形, 软件内置算法存在缠绕出的胎面与理想胎面偏差较大且缠绕效率低的问题, 故本文改用NURBS曲线对缠绕过程中的曲线仿形, 提出了一种基于NURBS曲线的轮胎胎面缠绕仿真算法. 实例验证结果表明, 所设计的胎面缠绕仿真算法缠绕的胎面形状符合国家标准和企业要求, 具有一致性好, 生产效率高等优点.
Abstract:The algorithm of the tread winding system configured in the open-loop control system for tread winding production features poor performance, and thus this study proposes a tread winding simulation algorithm based on the NURBS curve and verifies it with an example. At present, the tread winding simulation software of the open-loop control system for tire tread winding mostly uses straight lines and arcs for curve profiling in the winding process. The software’s built-in algorithm leads to a large deviation between the wound tread and the ideal tread and has a low winding efficiency. Therefore, this study uses the NURBS curve for curve profiling in the winding process and proposes a tire tread winding simulation algorithm based on the NURBS curve. The verification results show that the tread shape wound by the designed tread winding simulation algorithm meets the national standards and enterprise requirements and boasts good consistency and high production efficiency.
