PT Journal AU Gerlici, J Lovska, A TI Study of the Strength of the Open Wagon Hatch Door with Rectangular Corrugations under Static Loads SO Communications - Scientific Letters of the University of Zilina PY 2024 BP B216 EP B225 VL 26 IS 3 DI 10.26552/com.C.2024.039 WP https://komunikacie.uniza.sk/artkey/csl-202403-0012.php DE open wagon; hatch door; strength of the hatch door; improved hatch door SN 13354205 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. ER
