BALANCED ANALYSIS OF STANDING INDIVIDUAL PASSENGER IN THE CARRIAGE OF SUBWAY TRAIN

摘要

Nowadays, because of the development of the improvement of economy and living standard, passengers have a higher demand for comfort and safety of subway train.However, because the record of passenger volume in rail transit is refreshed continuously and large sums of passengers need to travel by rail transit during peak hours, subway trains are too crowded to enter and some of the passengers have to stay on railway platform to wait for the next train, and then series of problems,such as the platform and station hall getting more crowded, are caused.Therefore, the service levels of rail transit should be further improved to face with a huge passenger volume in order to keep passengers comfortale and safe.This study will research the dynamics law of body balance comprehensively according to biomechanics, and investigate the normal standing posture, age composition, span of boby, and stable angles of passengers, which are based on the characteristics of subway train whose acceleration and frequency of starting and braking are large and high, and analyze mechanical model of standing balance, and establish mechanical equations of body balance considering acceleration of train, span of foots, and angle between shoulders and traffic direction basing on moment of momentum and biomechanical principle.Then, individual balance of standing passenger will be analyzed, according to specific data.Finally, getting the maximum reasonable value of accelerations of starting and braking to provide a theoretical basis for the train traveling standard,which should meet the requirements of comfort and safety, and the design methods of subway train.
