An improved modelling and optimisation of rail vehicle design based on safety criterion
This paper deals with the modelling and the optimisation of a rail vehicle system moving in curved tracks running at high speeds. Based on the structural characteristics of the rail vehicle and its curved motion, we present an improved analytical quasi-static model. This model has the advantage of considering the roll motion. The improved model is validated through simulations, using the software ADAMS. The obtained model is used for the optimisation of the rail vehicle design. The safety criterion is evaluated using the derailment angle. A critical speed optimisation as a function of the radius of curvature and the rail vehicle design parameters is performed using genetic algorithm. The outcome of this work could help the designer in the choice of the adequate design parameters yielding the best compromise between the critical speed and the radius of curvature.
期刊介绍:
The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
