Study On The Structure Improvement Of A Car Under 25% Small Overlap Collision Conditions

The 25% small overlap frontal collision is hereinafter referred to as the 25% collision,which is the collision evaluation standard established by the United States IIHS in 2012 for the defects of the automobile frontal collision structure.It is the evaluation of the previous car collision 100% positive collision and 40% frontal collision.supplement.Although it is a new standard,the main engine manufacturers that sell cars on the US market have attached great importance and have come up with their own collision structural improvement programs.At present,the domestic auto market is developing rapidly.The awareness of selfowned brands for high-end vehicles is strong.At the same time,the high-speed development and R&D outlets for new energy vehicles have been ushered in.After 6 years of domestic research,25% of small-scale overlapping collisions have been achieved.For certain research,this article is not a test and verification form of the dissertation.Instead,it is based on the domestic research basis,and makes a holistic study of the structural improvement of the 25% small overlap collision with the subject background(modeling background)of this paper.25% of collisional energy absorption data from other papers is an overall study of the way and direction of 25% collision improvement.This comprehensive research conference covers all aspects of automobile structure.The purpose of this paper is to return to the initial heart of the automobile structure,guide the functional structure,and guide the structure of the process,to study the structural means for the automobile to deal with 25% of small overlap collisions,and to redevelop the structure of new energy vehicles.Improving the structure of the 25% collision of old cars,and redesigning the structure of the new platform with 25% of collisions,I believe will help.At present,the research basis in China has been made clear.The core problem of 25% collision is the intrusion of the passenger compartment.Today,the long-range pure electric vehicle is about to open in the future.The big intrusion not only affects the leg injury status of the members,but also relates to battery safety.Sex problems,redesigned electric platforms with high cruising range Regardless of the requirements of regulations,the structure design problem of 25% collision must be considered.This article is divided into several parts and explores areas such as bumpers,water tanks,firewalls,front finger beams,and floors.The ideas and methods of research are mainly illusions,imaginations,intuitions,and inspirations of irrational factors(author's design background)..The structure is determined by the shape,the function determines the structure,the cost determining mechanism,the spatial deciding structure,the process deciding structure,and the collision base deciding structure.Structured from three aspects.From here,if we want to increase the cost of simple improvements,how to design,how to design a new platform to be redesigned,to be converted into a pure power platform where we need to design how to start research.The results of the penny improvement penny,although this article did not evaluate the results through digital simulation,but this article to improve the results of the irrational factors predicted by the author to tell the reader.If readers are interested in the ideas for improvement of this article,they can model and verify themselves,which will make a contribution to the wave advancement of automotive structural improvements.
