Along with the rapid development of domestic urban rail transit and the acceleration, the national rail transit technology as an important issues of "11th five-year" plan, which the vehicles "safe" and "comfort" is the eternal theme in rail transit. In this paper, a stainless steel metro vehicle as the research object, research on stainless steel metro vehicle safety and comfort, the main contents are as follows:First of all, according to the three-dimensional model of a stainless steel subway car body establish the car body finite element analysis model, according to the regulations of EN12663standard of15kinds of load cases, carried out on the car body stiffness, static strength and fatigue strength finite element analysis, analysis of the simulation results meet the strength safety index; While according to the results of finite element analysis, the weak position of measuring points on the body are arranged for the body stiffness and strength test, and the test results and calculation results are compared in detail analysis, discuss the correlation of test and calculation analysis, induces the test and the simulation results are the cause of the error;Again, summed stainless steel subway cars acoustic design processes and control methods; stainless steel subway cars based on three-dimensional design, based on statistical energy analysis to establish vehicle acoustic simulation model of the passenger compartment for acoustic analysis; sound source via the vehicle control indicators and acoustic indicators eventually enable the passenger interior noise indicators meet the standard requirements; while the use of the vehicle acoustic test equipment line noise test study, test results evaluation vehicle acoustics with quality control methods and verify acoustics and acoustic simulation accuracy of the method;Finally, based on the vehicle passenger compartment and three-dimensional design of the air conditioning system, the establishment of the vehicle passenger compartment How simulation model for the simulation of airflow inside the passenger compartment; research passenger compartment outlet size and direction of the wind speed, the flow rate of air passenger head region and the entire cabin area mainstream airflow velocity and temperature distribution; based air conditioning system design criteria to assess the comfort of the passenger compartment; passenger room for the uneven distribution of velocity and temperature conditions, suggestions for improvement, and finally to the comfort inside the passenger compartment to meet the design requirements. K value means a vehicle test. insulation performance of the vehicle to meet the design requirements.
