摘要:
机车车辆轴重的提高和列车编组数量的增加会导致调车连挂冲击中的纵向冲动显著增大,从而带来一系列安全隐患。通过构建摩擦缓冲器动力学修正模型、车辆冲击动力学模型及车体—钩缓—车体串联模型等,研究了不同制动状态及不同阻抗特性缓冲器组合对车辆纵向冲动的影响。结果表明:缓冲器动力学修正模型能较好地模拟机车车辆调车连挂冲击中的缓冲器特性,以及制动阻力作用下的车钩力变化;车体—钩缓—车体串联模型能较好地模拟装配不同阻抗特性缓冲器的机车车辆连挂组合的冲击,对缓冲器的合理选用具有一定的理论指导价值。
Abstract:
Increase of axle load and wagon numbers of heavy haul train would generate larger longitudinal train impulse in the condition of shunting impact, and it would result in some dangerous problems. On the basis of draft gear dynamic modification model, the vehicle impact equation and vehicle-coupler-vehicle series model, the effect of different braking conditions and combinations of draft gears of different resistance characteristics on longitudinal impulse characteristics were studied. The results showed that the draft gear dynamic modification model could actually reflect the characteristic of draft gear in shunting impact, and the coupler force variation in brake condition; the vehicle-coupler-vehicle series model could simulate the impact of locomotive and freight vehicles equipped with different drafts gears well, and it had some guidance for selecting suitable draft gear.
