DESIGN OF THE MOTOR VEHICLES FROM THE ASPECT OF HIGH STRENGTH STEELS APPLICATIONS

Abstract

Design of the motor vehicles from the aspect of high strength steels applications is considered in this paper. Specific problems of applications in motor vehicles are put in correlations to characteristics and properties of this steel grade. The nature, characteristics and properties of high strength steels are briefly discussed in the paper to establish the set of influential factors related to design of motor vehicles from the aspect of high strength steels applications. High-strength low-alloy steels are the materials with currently fastest growing share of application in motor vehicles. Those steels have significantly different characteristics from the characteristics of conventional steels that they replaced. The market demands that are put on design of motor vehicles even enlarge the usage of high strength steels in motor vehicles. The advantages of usage of this steel grade are put in correlations with particular mechanical design procedures which are required by those applications. The concrete tasks in design procedures of motor vehicles which are related to applications of those steels are recognized in this paper. It is concluded in the paper that applications of high strength steels in motor vehicles put new significant perspectives in design, but, also, brings some problems that must be solved in process of design of motor vehicles. The applications of high strength steels in the elements of motor vehicles provide many positive effects on affordability, safety, reliability and duration of exploitation period. The full advantages of applications of high strength steels in motor vehicles can be realized only by optimization of its design procedures due to specific characteristics and properties of high strength steels.
