Abstract


Since the reform and opening up, China's highway construction and transportation has made remarkable achievements. The sharp increase in passenger car ownership and increased operating speed played a decisive role, not only to ease the pressure of the growing transportation, but also for the development of the national economy, especially along the road of economic development has brought vitality, but at the same time also led to serious traffic safety problem. Passenger cars as the main tool of the road passenger transport, its large capacity, less security, in the event of traffic accidents, casualties inevitable. Passenger is traveling in the mountains, security incidents can easily cause Qunsiqunshang serious harm to a significant impact on people's lives and property safety, social harmony and stability, and even develop into unstable factors. Passenger safety and the lives and property of the people closely in the cause government attaches great importance to industry sectors, but also become the focus of attention of the society. In all forms of traffic accidents resulting in serious injury collisions proportion of the highest, especially in the frontal impact the most. Of passenger cars, including China, the world's major car producing countries to develop a comprehensive, rigorous frontal crash safety regulations and real car crash test standards. Passenger's frontal crash safety research, however, relatively late, although some domestic and foreign enterprises and research institutions to conduct exploratory trials and studies, community attaches great importance, but has not yet been developed specifically for the bus frontal crash safety regulations or system of real vehicle frontal crash safety test methods, the security requirements of the bus body structure is still mainly focused on static rollover. Relying on the national scientific and technological support projects on the basis of analysis of the road traffic safety situation, with reference to domestic and foreign passenger car frontal crash regulations GB11551-2003 ECE/R94 C-NCAP and commercial vehicle cab crash test regulations ECE R29 test requirements, explicit nonlinear finite element program LS-DYNA 100% rigid barrier and pendulum method frontal crash finite element simulation analysis of a 6127-type passenger cars, respectively, to study the deformation characteristics of the type of bus head-on collision and crash safety, and security related to the front of the structure and the driver restraint system, and proposed measures to improve and optimize the structure of the passenger car and passenger front collision, explored the passenger front crash test the feasibility of using the pendulum method ; preliminary passenger frontal crash simulation standardized modeling approach and passenger frontal crash test methods and evaluation draft. The subject of research, real vehicle test design implementation and positive for the passenger front impact crash safety regulations formulated to provide a reference.
