摘要：The article studies how things stand in terms of the determination of the stress-strained state of the hatch cover of the gondola car when the cargo falls on the cover. The methods that are currently used were briefly reviewed. The calculation was performed using nonlinear dynamic analysis in CAE (Computer Aided Engineering) NX system.
