摘　　要：为实现跨坐式单轨列车既有低地板车辆结构优势,同时又能提高曲线通过性能,本文基于跨坐式单轨车辆耦合转向架,在相邻车体下部采用耦合转向架,端部车辆采用带有摇枕的单轴转向架,提出了跨坐式单轨列车总体方案。仿真分析表明:新型跨坐式单轨列车的端部转向架和两车之间的耦合转向架在圆曲线上基本能够处于径向位置,消除了走行轮的侧偏力和回正力矩,同时减小了导向轮的径向力。A new scheme of straddling monorail train was proposed based on the coupling bogie of straddling monorail vehicle. Coupled bogies were used at the adjacent car bodies and single-axle bogies with bolsters were used at the end of train. This new straddling monorail train not only realized the low floor structure of the car body, but also improved the curve passing performance. The simulation results showed that the end bogie and the coupled bogie could be in the radial position on the circular curve, eliminating the sideslip force and the return torque of the running wheel, and reducing the radial force of the guide wheel.
