軟臥客車
英文
sleeping carriage with cushioned berths-
The effect of car body elastic vibration on the ride comfort is analyzed. the ride comfort and acceleration responses of the car system with rigid car body model or elastic car body model are studied and compared. finally by using ansys / ls - dyna software, the finite element impact models of car body with a rigid wall have been set up, then the displacement, velocity, acceleration and energy variation of the car body are analyzed and compared for before and after lightening cases under the condition of impact speed 5. 8m / s and 11. 8m / s
本文利用ansys軟體建立了25k硬臥客車車體輕量化前後的有限元模型,計算了車體的強度、剛度和模態,並對輕量化前後的車體作了對比分析;然後,用nucars動力學分析軟體建立了25k硬臥客車系統的數學模型,分析了彈性振動對平穩性的影響,並對剛性車體和輕量化前後的彈性車體對平穩性和加速度響應的影響作了對比分析;最後用ansys / ls - dyna軟體建立了25k硬臥客車車體輕量化前後的動態顯式有限元模型,分別在5 . 8m / s和11 . 8m / s的速度下碰撞剛性墻,得到了車體的相對位移、速度、加速度和能量的變化過程,並作了對比分析。According to train marshalling and time when train stops, it computes seats allotment of hard seat, soft seat, hard berth and soft berth of all stations where the train stops. and then, we can adjust the results with production system to match our requirement
根據列車編組、停站時刻等數據,自動計算並完成線路方向上旅客列車在經由停車站軟(硬)臥(座)的票額分配,可利用產生式系統對票額分配的結果進行合理化調整。The results of the experiments have showed that the vibration of the head and the buttock mainly take place in the frequency of 0. 5 ~ 20hz, the vibration acceleration of the passenger ' s head on the high - level sleeper bus at highway does not exceed 1. 20 m / s2, the buttock ' s vibration acceleration is not more than 1. 00m / s2, however the acceleration of the legs " vibration is less than 0. 50m / s2. the vibration experiments of trains were done on the hard and soft berths in the mountain diverged line and the plain main railway, the data showed that the vibration of the passenger ' s head and pelvis mainly took place in the frequency of 0. 5 - 15hz, under this range, the acceleration of head ' s vibration do n ' t exceed 0. 80m / s2, the but tock ' s vibration acceleration is not more than 0. 40m / s, the legs " vibration acceleration is less than 0. 30m / s
數據分析表明,頭部和臀部振動主要發生在0 . 5hz 20hz ,高檔公路臥鋪客車在高速公路上,頭部振動加速度值一般不超過1 . 20m s ~ 2 ,臀部振動加速度值一般在1 . 00m s ~ 2以下,而腿部振動加速度值一般在0 . 50m s ~ 2以下;鐵路臥鋪客車臥姿乘客振動試驗分別在山區支線和平原干線上運行的硬臥及軟臥臥鋪進行,數據分析表明,頭部和臀部振動也主要發生在0 . 5 15hz ;平原干線的鐵路軟臥,頭部振動加速度不超過0 . 80m s ~ 2 ,臀部振動加速度值不超過0 . 40m s ~ 2 ,而腿部振動加速度值則在0 . 30m s ~ 2以下。
