Study On Transition Curve Parameter Standard Of Medium And Low Speed Maglev Traffic Based On Dynamics Analysis

Following the High-Speed railway transportation using in remote traffic in our country has approached to saturation in nowdays, developing the new pattern traffic like medium & low speed maglev technology using in short distance transportation will be more fit our country’s rapid developing in economy and tech, also could improve the expectation in high-usage of environment and meet the requirement from people in urban-rail and inter-city transit. Compared with popular short distance transit ways like metro and light railway at present, the medium & low speed maglev transit has marked superiority in train performance, noise pollution and project cost. As the line curve parameters will influence the cost and comfort level notably, so we need analysis the problem with pertinence.On basis of analyzing the similarities and differences between maglev and wheel track train, meanwhile the methods in confirming curve parameters, this paper use the multi-body system dynamics simulation software SIMPACK in building whole-train model and railway model with considering track irregularity on background of Zhuzhou southern locomotive factory. Studying on dynamic respond analysis of medium & low speed maglev train.The analysis mainly consider the comfort of passenger in comparison with dynamic respond indicators contained unbalanced centrifugal acceleration and change of the acceleration in context of three different transition curve including sine-shaped, cosine-shaped and convolution -shaped. Comprehensive several indicators, this paper put forward transition curve linetype fitting in medium & low speed maglev transit system. Verifying the outcome of simulation whether coincide to the theory’s change law by means of comparing static and dynamic response. Finally, taking a simulation on different curve radius with max curve passing velocity and contrast with comfort indicators on different length of transition curve, then give out the recommend minimum length of transition curve on different curve radius of medium & low speed maglev transit.
