| Hundred years have passed since the advent of the car. It bring convenience to people’slives, but also gives us a series of road traffic problems. At present, China’s road traffic safetysituation is not optimistic, and the situation of operation vehicles’ road traffic safety is evenmore worrying. The consequences of operating vehicle road traffic accidents are serious andhave bad social impact. The technical condition of the vehicle itself and operational securityrisks greatly related to the personal and property safety of the members of the vehicle. Thusdoing the research of the affection of the operating vehicle technology and security risks forroad safety has urgent practical significance.The article has made a detailed analysis of characteristics and factors of operatingvehicle road traffic accidents based on a large number of accident cases. Serious roadaccidents are considered as the most common operating vehicle accidents. The main factors ofserious road accidents are his vehicle technical condition and safety hazards. Summarize thetypes of frequent hot accidents in recent years. Take a combination of qualitative andquantitative methods. First establish hotspots traffic safety analysis model qualitative, thenquantitatively validate the model data through specific accident cases.On the basis of operating trucks long downhill braking systems heat recession accidentanalysis, combined with the mechanism and causes of brake thermal recession, structure andworking principle of drum brakes, according to the energy conservation law, establish thebrake drum temperature rise computing model and simulate in Matlab software. Using thespecific accident data to validate the feasibility of the model. Establish the operating truckwith a flat tire direction of instability model based on the operating system of truck tiredirection instability accident analysis, combined with the changes in the characteristics of theflat tire. Use Matlab Simulink software to simulate and analyze. Use specific accident data toverify the feasibility of the model.On the basis of the analysis of operating passenger car rollover accident, combined withthe basic principles of a vehicle rollover structure, establish operating passenger car rollovermodel. Simulate it in Matlab software and use specific accident data to verify the feasibility ofthe model. On the basis of analysis on the sleeper bus accidents, combined with the structureof the sleeper bus, proceed from the position and number of exits setting to establish sleeperbus occupant evacuation time calculation model. Simulate it in Matlab software, use specifictraffic accident data to verify the feasibility of the model. Conduct Countermeasure Research against the hot operating vehicle accidents. UseMatrix Laboratory (Matlab) to simulate the models established above, plotting partialdifferential element dynamic curve, analyzing the trend of curves. Put forward hotspotscountermeasures for all types of operating vehicles. And it has some practical significance... |
