中文摘要:基于弹性力学赫兹接触理论,对主轴箱在z轴不同位置时双滚珠丝杠副轴向刚度、角接触球轴承轴向刚度和直线导轨副线刚度进行分析,建立了静刚度模型。基于此模型,结合有限元仿真,得出永磁直线同步电动机法向力对机床刀具点的变形。仿真结果与实验结果对比表明,两者吻合很好,验证了静刚度模型的有效性。

Abstract:Based on the Hertz contact theory of elastic mechanics, a static stiffness model of double ball screws joint was built by analyzing the linear stiffness of double linear guide rails and the axial stiffness of double ball screw and ball bearing. The permanent magnet linear synchronous motor’s normal force affected the deformation of the feeding system. Based on the static stiffness model, deformation of the tool point was analyzed by finite element method and compared with the experimental results. The simulation results were in good agreement with measured data and indicated the accuracy of the static stiffness model. 

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.
