【摘要】：浮动负半径滚子推杆凸轮机构,是浮动推杆盘形凸轮机构、负半径滚子推杆盘形凸轮机构的组合创新,兼具两大类机构性能优点。基于浮动负半径滚子推杆凸轮机构的复杂性,求解的繁琐性,采用科学有效的可视影射尺寸综合方法。提出运动连通、运动保真、传动性能和接触强度四项重要约束条件,构建相对应的解析判据及性能评价体系。依据约束条件,构建面向尺度综合的统一的性能评价指标映射域,建立各性能指标间错综复杂的多元耦合关系,发现和揭示诸性能评价指标和尺寸参数间的映射规律。通过本文对象机构尺寸分析综合理论完整的探索研究,得到诸多有重要意义的创新性结论--"谷底点/脊点/脊线"、"非劣解区域/劣解域"、"双优点"、"谷/脊底线"和"壑底点"等的重要内涵和求解方法,对充分发挥对象机构的优越功能和性能,推动对象机构更广泛付诸工程应用,具有重要理论价值和实际意义。
[Abstract]:The floating negative radius roller push rod cam mechanism is the combination innovation of the floating push rod disc cam mechanism and the negative radius roller push rod disk cam mechanism. Based on the complexity of floating negative radius roller push rod cam mechanism and the complexity of solving the problem, a scientific and effective method of visual projection dimension synthesis is adopted. The motion connectivity and motion fidelity are proposed. According to the four important constraint conditions of transmission performance and contact strength, the corresponding analytical criterion and performance evaluation system are constructed. According to the constraint conditions, a unified mapping domain of performance evaluation index oriented to scale synthesis is constructed. The complex multi-coupling relationship among the performance indexes is established, and the mapping laws between the performance evaluation indexes and the dimension parameters are discovered and revealed. Through the research of the comprehensive theory of the size analysis of the object mechanism in this paper, a complete exploration and research is carried out. Many important and innovative conclusions are obtained, such as "valley bottom / ridge / ridge", "non-inferior region / region" and "double advantages". The important connotation and solution method of "valley / ridge bottom line" and "ravine bottom point" can give full play to the superior function and performance of the object mechanism and promote the object mechanism to be applied more widely in engineering. It has important theoretical value and practical significance.
