Analysis Of High Speed Train Carbody Design Standard

High speed train is very important in the high speed railway technology. So the research of high speed train carbody structural strength design standard and test criterion becomes indispensable. However, domestic high speed train is under studying and the only one high speed train carbody structural strength design standard is < strength design test appraisal temporary stipulation for 200km/h and higher speed railway train >. It is apparently not enough to high speed train design. So that, it is very significative to bring forward high speed train carbody structural primary referenced evidence.Carbody is a very important part of high speed train research. The carbody not only transfer the traction and brake force to coupler but also bear load from various equipments and lognitudinal or horizontal impact load when it is running. Therefore the carbody must be with enough strength and rigid and meet requirements of relative technology standard in order to guarantee the train security and stabilization. It is need design standard and appraisal criterion that fit the fact.Analyzing and comparing carbody design standard EN12663, UIC566, JIS E7105 and < strength design test appraisal temporary stipulation for 200km/h and higher speed railway train >, absorbing foreign bodyshell design concept, then bringing forward preparatory domestic high speed train carbody design standard.
