中文摘要:目前运用较多的柔性运动副基本上只能产生微细变形,适用于微动领域,缺少能产生宏观尺度变形的柔性运动副。在弹性曲板变形理论的基础上设计出一种新型柔性转动副,可以满足宏观尺寸下的变形要求。通过理论分析建立其柔度矩阵,分析其转动刚度与转动误差,利用Matlab进行了理论计算,并进行了Ansys软件仿真与实体模型试验。结果表明:理论计算与仿真的转动刚度相对误差为5.6%,转动误差相对误差为3.4%,通过试验验证了转动刚度和转动误差相对角度变形的变化规律,说明对该新型大变形柔性转动副的柔度分析正确。

Abstract:The disadvantage of current compliant pairs used in micro-displacement fields are that they produce micro-deformation rather than macro-scale deformation. In order to solve this problem, a new compliant revolute pair was proposed based on the theory of elastic deformation which can provide macro-scale deformation according to its own elastic deformation. The model of flexibility matrix was established, and rotation error was calculated with Matlab software and analyzed in Ansys. The results showed that the relative rotational stiffness error was 5.6% and relative rotation error was 3.4% according to the two methods. Finally, a test of the compliant revolute pair was carried out to justify the two above-mentioned results. It showed the flexibility analysis is reasonable.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
