RT Journal Article SR Electronic A1 Gerlici, Juraj A1 Lovska, Alyona T1 Study of the Strength of the Open Wagon Hatch Door with Rectangular Corrugations under Static Loads JF Communications - Scientific Letters of the University of Zilina YR 2024 VO 26 IS 3 SP B216 OP B225 DO 10.26552/com.C.2024.039 UL https://komunikacie.uniza.sk/artkey/csl-202403-0012.php AB Rail transport has been the leading sector of the whole transport network. In order to improve the efficiency of its functioning, it is important to develop measures that may help reduce the maintenance cost. To improve the open wagon hatch door strength, it is proposed to make it with rectangular corrugations. The results of calculations show that, taking into account the proposed solution, the weight of the improved hatch door is almost 10% lower than the weight of a typical one.
