Research On Subway Passenger Flow Model Based On Fluid Mechanics Theory

With the nationwide boom in rail transit construction,large and medium-sized cities across the country have increased investment in rail transit constructio.However,much attention has been paid to the optimization of railway lines in the construction of existing rail transit.Although the scale of site facilities can be determined by the subway design specification,there is a great defect in the specification:there is no consideration that the passenger flow is moving and the design of the facility is only to meet the maximum passenger flow requirement of this point,but if the passenger flow is flowing,the passenger flow will be delayed if there is one link in the system Reduce the efficiency of the whole system.In view of the flow problem of passenger flow,the theory of fluid mechanics is applied to the study of passenger flow,and the flow trend of passenger flow is simulated and simulated,which makes the flow of passenger flow a predictable factor.In this paper,the essentials and properties of fluid mechanics are compared with the factors and properties of the passenger flow,and the meaning is replaced.For the special continuity properties of fluid mechanics,the theory of the continuity of passenger flow and the pressure on the passenger flow are put forward with reference to the knowledge of fluid mechanics and the study of the passenger flow.The theory.Based on the theory of fluid mechanics,the three equations of passenger flow are derived.The article sets up 6 kinds of staircase width,and uses the fluid mechanics software to analyze the relationship between the speed of passenger flow and the pressure on the facilities under the 6 staircases,which can provide data reference for the facilities in the later design site.The main achievements of this paper are as follows:the theory of fluid mechanics can be applied to the study of passenger flow in railway station platform under certain conditions,and the model of passenger flow is deduced and the cause of traffic congestion on the platform can be explained according to the model.6 kinds of staircase width and platform are modeled,and the trend of velocity and pressure is analyzed by staircase width to provide data reference for the setting of staircase width.
