| 目的 对某钢材公司现有田字型木托架结构进行分析，并对其结构进行改进优化，获得兼顾木托架承载性能与节约成本、降低使用木材资源的设计方法。方法 通过建立田字型和外伸梁型（3纵梁×2横梁）木托架的堆存工况力学模型，对木托架的受力情况进行理论推导与研究，并根据结果制定出外伸梁型木托架的优化设计方案，并应用有限元法对吊运和多层堆存工况进行仿真，求出木托架结构的应力响应，以检验优化设计方案的正确性。结果 采用外伸梁型木托架代替田字型的木托架在堆放工况下弯曲应力低，相同的条件下外伸梁型木托架能够承受田字型木托架所承载载荷，且成本更低。结论 外伸梁型木托架更能节约木材和其他耗材，具有很好的实际工程价值。 |

| The work aims to analyze the existing matts-shaped wooden pallet of some steel company and improve & optimize its structure, so as to achieve the design method that gives considerations to both load-bearing property and cost saving and reduces the timbers to be used. After the mechanical model of stockpiling conditions for matts-shaped and overhang-beam type wooden pallets (with 3 stringers and 3 beams) was built, the theoretical deduction and research of force bearing conditions of wooden pallets were conducted. The optimized design scheme was made according to the results. The lifting and multi-stockpiling conditions in finite element method were simulated to obtain the stress response of wooden pallets. By doing so, the correctness of optimized design scheme was verified. By replacing the matts-shaped wooden pallets, the overhang-beam type wooden pallets had less bending stress under the stockpiling. Under the same conditions, the overhand-beam type wooden pallets could bear the same load applied to matts-shaped ones with lower costs. The overhang-beam type wooden pallets can save timbers, other consumables and manufacturing costs, and have a good value in engineering application. |
