中文摘要:在建立永磁直线同步电动机驱动结构机械模型的基础上,采用有限元仿真分析运动部件在不同位置时法向力变化对龙门结构横梁变形的影响,得出横梁在y轴方向的变形曲线。实验测得横梁背面变形,并与仿真结果对比分析,得出电动机定子磁场对应的法向力。实验结果验证了仿真结果的正确性。

Abstract:On the basis of permanent magnet linear synchronous motor (PMLSM) feeding system mechanical model, effects of normal force of moving parts in different stroke to deformation of a gantry type beam were analyzed by finite element method. A curve corresponding to y irectional deformation of the beam was achieved and the deformation of the beam was measured. The normal force of PMLSM was achieved by finite element simulation and relevant experiments. Deformation of the tool point was analyzed by finite element method and compared with the experimental results. The simulation results were verified to be reliable. 

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.
