Study on Initial Construction Length of EMS High-speed Maglev Engineering Test Line
Research purposes:China's EMS high-speed maglev has the conditions to promote engineering testing and demonstration operation line construction,and it is urgent to build an engineering test line to verify key technologies of high-speed maglev.This paper starts with the initial test requirements of EMS high-speed maglev engineering test line.The initial construction of the engineering test line does not consider ride comfort,and tries to use larger acceleration and deceleration speeds to reduce the length of the initial test line construction while meeting the requirements of initial speed testing,saving initial test line engineering investment.Research conclusions:(1)The high-speed maglev engineering test line is mainly a test to confirm various performance and practical goals at a speed of 600 kilometers per hour.(2)The initial construction length of the engineering test line must meet the requirements of the minimum distance for train acceleration and deceleration,as well as a certain uniform speed running distance.When the parameters of the domestically produced 600 km/h high-speed maglev train are fixed,the average acceleration and deceleration mainly depend on the rated voltage and maximum current of the traction converter.Through matching simulation calculation of the power supply system,the lighter the vehicle,the shorter the stator segment length,the greater the vehicle acceleration that can be provided,and the shorter the initial engineering test line construction length.(3)The research conclusion can provide reference for the construction of the engineering test line of the EMS high-speed maglev railway.
