    摘要:

    在AIP中創(chuàng)建蘋果起苗鏟三維參數化特征模型,,根據起苗鏟結構、材料,、載荷和受力情況等,,利用內嵌于AIP的ANSYS技術模塊創(chuàng)建了起苗鏟三維有限元模型,劃分了有限元網格,,獲得了起苗鏟三維應力,、變形和安全系數。根據設計要求和分析結果,,將起苗鏟結構改進為L形,,節(jié)省了材料,降低了工作阻力,,安全系數達到設計要求,。通過樣機起苗試驗,改進的起苗鏟工作阻力小,、起苗作業(yè)可靠,,取得了預期的效果。

    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.
