CALCULATION OF STRENGTH OF HALF WAGON COVER MADE OF POLYMERIC COMPOSITE MATERIAL

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