基于simpack仿真的铁路超限货物动态运输安全研究

Safety of railway out-of-gauge goods dynamic transportation based on simpack simulation

为量化分析各因素在安全运输过程中的影响程度,以车辆滑移、车辆侧翻、货物位移、货物滚动为安全指标,建立了铁路超限货物运输的车辆-道路模型,运用sim pack软件对铁路超限货物运输安全过程进行动态仿真。结果表明,重心横向偏移量、重车重心高和超限等级对起到主要影响。

Vehicle-road reliability and safety simulation model was established to quantitatively analyze the influence of safety factors,such as the vehicle slip,vehicle rollover,goods displacement,goods rolling,on railway out-of-gauge goods safety transportation process.Dynamic simulation of railway out-of-gauge goods safety transportation process was made based on simpack simulation.The results indicated that the lateral off set of center of gravity,the gravitational center height of heavy vehicle and the classification of out-of-gauge freight played a major impact.
