【摘要】：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。
[Abstract]:Aim to analyze the existing field type wood bracket structure of a steel company and optimize its structure to obtain a design method that takes account of the bearing capacity and cost saving of wood bracket and reduces the use of wood resources. Methods by establishing the mechanical model of the storage condition of field type and extension beam type (3 longitudinal beam 脳 2 cross beam), the mechanical model of the mechanical condition of the wood bracket was deduced and studied theoretically, and the optimum design scheme of the extended beam type wood bracket was worked out according to the results. The finite element method is used to simulate the hoisting and multi-layer storage conditions, and the stress response of the wooden bracket structure is obtained to verify the correctness of the optimal design scheme. Results the bending stress of the wood bracket with outstretched beam type instead of the field type is low under the stacking condition. Under the same condition, the extension beam type wood bracket can bear the load of the field type wood bracket, and the cost is lower. Conclusion Extended-beam bracket can save wood and other consumables and has good practical engineering value.
