摘要

本文介绍了吊舱舱盖改进设计强度的计算机模拟结果。改进的一个特点是生产了一片聚合物复合材料,并用水平片覆盖U形型材进行粘合。同时,与典型横截面相比,改进的捆扎设计相对于横轴的横截面阻力增加了17.5%。值得注意的是,所提出的舱口盖的质量比典型设计低12%。为了确定吊舱舱盖设计方案的主要强度指标,对其载荷的主要方案进行了计算。研究发现,考虑到所提出的解决方案,舱口盖片中的最大应力比标准设计低25%,在装订中低10%。所进行的研究将有助于减少吊舱舱口盖在运行中的损坏和维护费用,也将对吊舱的现代设计有有益的发展。

CALCULATION OF STRENGTH OF HALF WAGON COVER MADE OF POLYMERIC COMPOSITE MATERIAL
The article presents the results of computer simulation of the strength of the improved design of the hatch cover of the gondola. A feature of the improvement is the production of a sheet of polymer composite material, and binding - from a U-shaped profile covered with a horizontal sheet. At the same time, the cross-sectional resistance of the improved strapping design relative to the transverse axis increases by 17.5% compared to a typical cross-section. It is important to say that the proposed hatch cover has a mass 12% lower than the typical design. To determine the main strength indicators of the proposed design of the hatch cover of the gondola, the calculation was performed for the main schemes of its load. It was found that, taking into account the proposed solutions, the maximum stresses in the sheet of the hatch cover are 25% lower than in the standard design, and in the binding - by 10%. The conducted researches will help to reduce damages of covers of hatches in operation and expenses for the maintenance of gondola cars, and also will be useful developments at designing of their modern designs.
