| 中文摘要 | 隨著社會的進步,對農產品的運輸以及運輸過程中的儲存要求越來越高,廂式農用車成為農產品物流環節的重要交通工具。而車廂作為廂式農用車中的關鍵結構之一,在農產品的運載過程中發揮著至關重要的作用。以廂式農用車的車廂為研究物件,分析研究車廂存在的問題,然後通過三維軟體建模,在有限元軟體中對車廂及導軌進行兩種工況下的靜力學分析以及疲勞分析,接著在此基礎上開始結構優化,提出框架結構設計、導軌加強梁的增加等結構改進,從而消除邊板受力,減少裂縫現象的發生以及推板發生局部斷裂或者變形過大的現象,通過對優化後的結構進行驗證,得出優化後的結構滿足設計要求,提高車廂的使用壽命。 |
| 英文摘要 | With the progress of society, the transportation and storage requirements for agricultural products are becoming increasingly high, and box type agricultural vehicles have become an important means of transportation in the logistics of agricultural products. As one of the key structures in box type agricultural vehicles, the carriage plays a crucial role in the transportation of agricultural products. Taking the carriage of a box type agricultural vehicle as the research object, the problems existing in the carriage are analyzed and studied. Then, through three-dimensional software modeling, static and fatigue analysis of the carriage and guide rail under two working conditions are carried out in finite element software. Based on this, structural optimization is started, and structural improvements such as frame structure design and the addition of guide rail reinforcement beams are proposed to eliminate the stress on the side plates, reduce the occurrence of cracks, and prevent local fracture or excessive deformation of the scraper. Through verification of the optimized structure, it is concluded that the optimized structure meets the design requirements and improves the service life of the carriage. |
