摘要
目的针对传统木托架在钢卷包装运输过程中存在的适应能力差、强度不足和使用寿命短等缺陷,根据某企业的需求,设计了一种尺寸可调节、可承载不同规格立式钢卷的十字型钢托架结构。方法该结构主要由十字型连接件和4个可伸缩的托架臂构成,通过可伸缩托架臂设计,实现了尺寸的可调节功能。结果对托架进行抗弯强度和刚度计算,得出托架的最大应力和最大变形分别为50.23MPa和0.54 mm。对托架进行承载钢卷时静态有限元软件验证的结果分别为50 MPa和0.64 mm。结论该托架力学性能的分析计算结果与有限元仿真结果基本相符,表明其承载能力是合格的。
Objective Aiming at traditional wooden brackets＇ various defects including poor adaptability, insufficient strength and short lifespan in packaging and transportation of steel coils, and a certain enterprise＇ s needs an adjustable, a removable, recoverable new structure was designed for vertical roll cross-shaped steel bracket. Methods This structure was mainly composed of cross connectors and four retractable bracket arms. The bracket arms could stretch out and draw back freely, and the bracket could adjust its size. Results When analyzing the bending strength and rigidity, the maximal stress and maximal deformation of the bracket were 50.23 MPa and 0.54 mm, respectively. The corresponding finite element results were 50 MPa and 0.64 mm, respectively. Conclusion The finite element simulation results and theoretical calculation results were basically consistent, so the design of the new cross bracket structure was reasonable.
