Study on the Strength of 35t Coiled Steel Pallet for 100t Gondola Car

Abstract

The Coiled Steel safety transportation has become an important part of railway freight transportation. Due to the special shape and heavy-weight of coiled steel, loading and reinforcing is very complexity, Displacement or rolling is much more likely to happen in transit. It will lead to eccentric loading, unbalanced loading, freight vehicle damaging, or serious accident due to coiled steel falls down from freight vehicle. At present, the coiled steel produced are larger in weight, larger in diameter and wider in plate width, with a maximum weight of 35t. The 100t gondola car is generally C100 and C100 A. It has the advantages of longer length, larger load and larger capacity in the middle. It is the best choice for loading larger weight coiled steel. This paper used SolidWorks to build the model according to the design structure of the special coiled steel pallet for loading 35t coiled steel on 100t gondola car. Then the stress distribution of the pallet is obtained through the strength simulation experiment. The results show that the maximum stress of the pallet occurs at the ribs in the middle of the clamp on the side of the pallet, which exceeds the allowable stress of the material. Finally, the pallet is optimized to meet the actual transport requirements.
