摘要

卡车的用途多种多样，但主要用途是货物运输。当货物运输时，卡车的悬架载荷很大，因此故障也最常发生在悬架元件上。对于拖车的车轴，管状结构会发生故障，它们会开裂。需要进行轴故障调查以确定故障的原因。本文对三轴汽车挂车悬架进行了分析。通过轴失效分析和轴向变形建模，确定了卡车挂车悬架轴失效的趋势和原因。对不同车轴采用管状结构，车轴壁厚分别为9和11 mm的情况进行了建模。给出了汽车挂车悬架轴的视觉失效分析和不同几何参数下悬架轴变形的有限元建模结果。对结果进行了讨论并得出了结论。

THE TRUCK TRAILER SUSPENSION AXLES FAILURE ANALYSIS AND MODELLING

The purpose of trucks is very diverse, but the main purpose is freight transportation. When cargos are transported, the truck’s suspensions are heavily loaded, so failures also occur most often in the suspension elements. For axles of trailers – tubular construction failures occur, they crack. Axle failure investigations are required to determine the cause of the failure. The paper analyses three-axle truck trailer suspension. Axle failure analysis and axial deformation modelling were performed to determine trends and causes of truck trailer suspension axle failures. Different cases with axles of tubular construction with wall thicknesses of 9 and 11 mm were modelled. The paper presented visual failure analysis of truck trailers suspension axles and finite element modelling results of axle’s deformation of different geometrical parameters. The results were discussed and conclusions were drawn.

期刊介绍： At present, transport is one of the key branches playing a crucial role in the development of economy. Reliable and properly organized transport services are required for a professional performance of industry, construction and agriculture. The public mood and efficiency of work also largely depend on the valuable functions of a carefully chosen transport system. A steady increase in transportation is accompanied by growing demands for a higher quality of transport services and optimum efficiency of transport performance. Currently, joint efforts taken by the transport experts and governing institutions of the country are required to develop and enhance the performance of the national transport system conducting theoretical and empirical research. TRANSPORT is an international peer-reviewed journal covering main aspects of transport and providing a source of information for the engineer and the applied scientist. The journal TRANSPORT publishes articles in the fields of: transport policy; fundamentals of the transport system; technology for carrying passengers and freight using road, railway, inland waterways, sea and air transport; technology for multimodal transportation and logistics; loading technology; roads, railways; airports, ports, transport terminals; traffic safety and environment protection; design, manufacture and exploitation of motor vehicles; pipeline transport; transport energetics; fuels, lubricants and maintenance materials; teamwork of customs and transport; transport information technologies; transport economics and management; transport standards; transport educology and history, etc.
