基於ANASYS的農用叉裝車伸縮臂的有限元分析與優化
Finite Element Analysis and Optimization of Agricultural Forklift Telescopic Arm Based on ANASYS
摘要
首先，以常用國產農用叉裝車伸縮臂為研究物件，利用Solid Works軟體對其零部件進行了三維建模，並對其進行組裝，得到三維立體的伸縮臂結構。其次，將建好的伸縮臂三維模型導入ANSYS Workbench軟體中，在典型工況下對其進行了靜力學和模態的有限元分析，得出在不同工況下的應力雲圖、變形雲圖以及伸縮臂的動態特性和振動頻率。最後，依據原結構伸縮臂有限元分析結果，對農用叉裝車伸縮臂進行了結構優化設計，通過結構的強化提高其強度和剛性的性能，在強化後的結構基礎上對其局部減輕重量實現輕量化的目的。並且對優化後的伸縮臂進行了疲勞性能的分析，結果顯示是符合設計要求的。該優化方案既有效地提高了農用叉裝車的安全係數，又降低了製造成本。

Firstly, taking the commonly used domestic agricultural forklift telescopic arm as the research object, the components were 3D modeled using Solid Works software and assembled to obtain a three-dimensional telescopic arm structure. Secondly, the established 3D model of the telescopic arm was imported into ANSYS Workbench software, and static and modal finite element analyses were conducted under typical working conditions to obtain stress and deformation cloud maps, as well as the dynamic characteristics and vibration frequencies of the telescopic arm under different working conditions. Finally, based on the finite element analysis results of the original structure of the telescopic arm, the structural optimization design of the agricultural forklift telescopic arm was carried out, and its strength and rigidity performance were improved through structural reinforcement. On the basis of the reinforced structure, local weight reduction was achieved to achieve the goal of lightweighting. And the fatigue performance of the optimized telescopic arm was analyzed, and the results showed that it meets the design requirements. This optimization scheme effectively improves the safety factor of agricultural forklift trucks and reduces manufacturing costs.
