摘　　要：为研究跨座式单轨曲线梁的力学特性，以重庆跨座式单轨交通袁家岗至谢家弯区段的曲线轨道梁为研究对象，利用ANSYS的二次开发功能对其自振特性和车辆荷载下的静、动力响应进行了计算分析。结果表明：该轨道梁有较高的整体刚度、强度；桥墩有较大的刚度和安全性；在10—50km／h车速范围内，车辆能安全通过该曲线梁。To study the mechanical properties of the curved track beam of straddle type monorail tran- sit, the curved track beam in the section of the monorail transit from Yuanjiagang to Xiejiawan in Chongqing City was selected as the research object and the secondary development function of ANSYS was used to calculate the natural vibration characteristic, static load and dynamic load response of the beam. The results of the calculation show that the curved beam and bridge piers have high global ri- gidity, strength and safety. The train can safely go through the curved beam with running velocity of 10 ~ 50 km/h.
