摘要
针对子午线轮胎成型装备自主创新需求,提出并研究了一种新型结构紧凑、大伸缩比、高刚度的子午线轮胎成型鼓.在系统阐述其结构与传动原理的基础上,建立了成型鼓内、外瓦板各基本伸缩单元实现轴/径向伸缩运动的数学模型及其几何与运动约束方程,给出了该类成型鼓的一般设计思路和方法,并以压力角为优化目标,实现了成型鼓导向机构尺度优化设计.在此基础上,通过计算机仿真验证了设计方法的正确性和有效性.研究结果对这类新型成型鼓的工程样机的研制提供了重要的理论依据.
To meet the demand of innovation in radial tire building equipment, a new type of tire building drum, with compact structure, large stretching ratio and high stiffness, was presented and studied. Based on the systematic description of its structure and transmission principle, the mathematical model and equation of geometry and motion constraints for the basic telescopic unit of both inside and outside tiles were established. The general design ideas and methods of this type of mechanism were given. Dimension optimization for tile guiding mechanism was carried out by taking pressure angle as object function. On this basis, the correctness and effectiveness of the approach were validated through simulation. The research lays an important theoretical foundation for developing the engineering prototype of this novel tire building drum.
