Abstract
Abstract: We propose the predicting passenger railway rolling stock safety technique. The technique is based on the methods of mathematical modeling using the world-famous industrial software systems. The criteria for passenger rolling stock safety is to ensure traffic safety and dynamic parameters, regulated by the normative documents, the strength of load-bearing structures in all operational modes, reliability and durability. When evaluating safety parameters we use solid modeling, finite element analysis of static and dynamic setting, taking into account geometrical and physical nonlinearities, cycle fatigue model, given in the linear fatigue damage summation hypothesis, as well as nonlinear fracture mechanics approaches and structure survivability. We consider the rolling stock operation modes, taking into account the traffic on the road straight sections, in curves and turnouts, starting and braking, as well as shunting collisions. Technique was successfully tested on the passenger car modern design, produced by the Tver Carriage Works and is implementing at the Russian car-building enterprises. Key words: Forecasting Safety Technique Passenger car Traffic safety Dynamics Durability Endurance Fatigue life Reliability Rolling stock Finite element model Solid modeling Stress-strain state INTRODUCTION The developing methodology core is the car
