中文摘要:在AIP中创建苹果起苗铲三维参数化特征模型,根据起苗铲结构、材料、载荷和受力情况等,利用内嵌于AIP的ANSYS技术模块创建了起苗铲三维有限元模型,划分了有限元网格,获得了起苗铲三维应力、变形和安全系数。根据设计要求和分析结果,将起苗铲结构改进为L形,节省了材料,降低了工作阻力,安全系数达到设计要求。通过样机起苗试验,改进的起苗铲工作阻力小、起苗作业可靠,取得了预期的效果。

Abstract:The 3-D parameterized model of apple seeding lifter was created using autodesk inventor professional (AIP) system. The finite element analysis (FEA) of the lifter were performed through ANSYS technology embedded in AIP analysis types based on the structure, material, loads and forces of the lifter, the 3-D FEA mesh was created, and stress, displacement, and safety factor were obtained after finite element calculation. Then some modifications of lifter configuration were made according to the FEA results. The new lifter with L shape could save materials, reduce resistance. The safety factor could also achieve design purpose. The experiment of lifting seeding results showed that the lifter could provide better working performance with less resistance and obtain the expected effect.

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.
