摘要:
以轨道客车司机室端吸能结构为研究对象,提出一种基于缺口导向分级触发的吸能结构,并采用三维仿真分析方法对该吸能区结构进行优化分析。另外,对优化后的吸能区结构进行全尺寸冲击试验验证。试验结果表明,仿真分析在能量吸收、压溃行程和平台力方面的误差可保持在10%以内。
Abstracts:
Taking the energy absorption structure at the cab end of rail transit vehicle as the research object, a gap-oriented hierarchical triggered energy absorbing structure is proposed, a three-dimensional simulation analysis is used to optimize the energy absorption structure. Then, the optimized absorption structure is validated with a full-scale impact test. The test result shows that the errors of the simulation analysis could be controlled within 10% for energy absorption, displacement stroke and the platform force.
