【摘要】 中低速磁悬浮列车以安全舒适、低噪声、爬坡能力强、工程造价低等特点非常适合作为城市轨道交通运输工具,大力发展城轨磁悬浮交通对解决我国大城市交通问题有重要意义。目前,城轨磁悬浮交通建设还没有规范,为大力发展城市轨道磁浮交通,建设部制定了编制《城轨磁浮交通设计规范》的计划。本文研究了确定城轨磁悬浮交通线路平面技术条件的方法,给出了线路设计参数的建议值,并用车线动力学对参数进行了检算。本文的研究可以为线路规范的编写提供科学依据。本文采用比较分析的研究方法,通过分析中低速磁悬浮列车和中低速轮轨列车的不同之处,并借鉴中低速轮轨列车线路标准的确定方法,研究总结了城轨磁悬浮交通线路平面技术条件的确定方法。其中平面最小曲线半径是由轨道梁横坡和允许未被平衡离心加速度决定的。城轨磁浮交通线路应该选用三次抛物线型缓和曲线。缓和曲线长度是由侧向加速度时变率和横坡角扭转率决定的。最小夹直线、夹圆曲线是由列车在一个振动周期通过的线路长度决定的。并分析研究了上述这些限制条件的限制值,计算出了线路平面技术条件设计参数。本文还研究了中低速磁悬浮列车的车线动力学,分析磁悬浮列车通过线路平面曲线时所受到的各种力,根据西南交通大学的磁浮车辆动力学模型,推导出了列车通过曲线的动力学方程。并用c++语言编写了求解程序,仿真计算了列车在曲线上行驶的各项舒适度值。因为确定城轨磁浮交通线路平面技术条件主要的限制因素是旅客舒适度,所以验证了本文给出的线路设计参数是合理的,并且验证了本文对城轨磁悬浮交通线路平面技术条件的确定方法是正确的。更多还原

【Abstract】 The low-speed maglev train has so many features as safe and comfortable,strong climbing ability, low cost, low noise and small the environmental impact . It is very suitable for the city transport in the volume . Vigorously developing Maglev urban rail transport is of great significance to solve the traffic problems in China’s large cities. At present, city magnetic levitation rail construction has not regulate traffic. In order to improve urban transport capacity and vigorously develop city maglev rail traffic. Construction plan to establishment norms of city Maglev rail traffic. This study can provide a scientific basis.This study using comparative analysis of research methods, summed up the method how the urban rail transport lines planar magnetic levitation technology determining through analysing the differences of low-speed maglev train and in the low-speed wheel-rail trains. The minimum curve radius is determined by track beam transverse and centrifugal acceleration . Three parabolic curve easing is choiced . Easing curve length is determined by wang slope angle reverse rate and lateral acceleration time-varying rate . Minimum linear folder, folder circular curve is determined by the train vibration cycle . This study has calculated these design parameters.This study also studied the vehicle dynamics of the low-speed maglev train . According to the Southwest Jiaotong University maglev vehicle dynamics model, analysised the force of the vehicle through the plane curve. Having derived the equations of motion .Simulation calculation the line Parameters by conputer ccording to equation, preparating the calculation procedures using C++. Through the line parameter calculation, verifing the calculation method is correct and line parameter is reasonable.更多还原
