摘　　要：针对高速列车驶出兰新第二双线特有防风明洞工程时存在突变气动载荷,探讨了抗侧滚扭杆对国内某型高速列车抗倾覆安全性的影响.采用日本Yu Hibino详细解析式方法,针对国内某型高速列车建立其车辆倾覆受力及倾覆力学模型,对车速、风速和风向角变化时,抗侧滚扭杆对该型高速列车的倾覆系数和侧滚角等的影响进行了计算研究.分析结果表明:抗侧滚扭杆有效改善了该型高速列车的抗倾覆性能.增设抗侧滚扭杆后,车辆倾覆系数降低约10%,侧滚角降低约75%.The effect of antiroll torsion bar on the overturning of a type of China Railway Highspeed （CRH） is studied, for the high-speed train will suffer sudden change of aerodynamic load when it exits the export of the anti-wind tunnel on the second Lanzhou-Xinjiang high-speed rail- way. The load acting on the vechile and the mechanical model are set up based on the detailed e- quation which is used to evaluate the anti-overturning performance by Yu Hibino in Japan. The contribution of the antiroll torsion bar to overturning coefficient and vehicle body roll angle is studied in the combination of various train speeds, wind speeds and wind angles. The result shows that the overturning coefficient is increased by 10% and the roll angel is decreased by 75%. The antiroll torsion bar can improve the anti-overturning performance of such CRH.
