    摘要:

    在AIP中創(chuàng)建蘋果起苗鏟三維參數(shù)化特征模型，根據(jù)起苗鏟結(jié)構(gòu)、材料、載荷和受力情況等，利用內(nèi)嵌于AIP的ANSYS技術(shù)模塊創(chuàng)建了起苗鏟三維有限元模型，劃分了有限元網(wǎng)格，獲得了起苗鏟三維應(yīng)力、變形和安全系數(shù)。根據(jù)設(shè)計(jì)要求和分析結(jié)果，將起苗鏟結(jié)構(gòu)改進(jìn)為L形，節(jié)省了材料，降低了工作阻力，安全系數(shù)達(dá)到設(shè)計(jì)要求。通過樣機(jī)起苗試驗(yàn)，改進(jìn)的起苗鏟工作阻力小、起苗作業(yè)可靠，取得了預(yù)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.
