【摘要】：在公路橫風(fēng)多發(fā)區(qū)域,因突發(fā)性及隱蔽性等特點(diǎn),極易對(duì)車(chē)輛安全行駛造成威脅,常導(dǎo)致惡性交通事故。目前國(guó)內(nèi)對(duì)橫風(fēng)多發(fā)路段汽車(chē)的行車(chē)安全限速研究相對(duì)較少,較難滿(mǎn)足橫風(fēng)氣象下的安全需求。此外,橫風(fēng)作用下,不同車(chē)輛抗風(fēng)能力有很大差異,若能對(duì)大小車(chē)輛區(qū)別限速,則對(duì)交通管理以及安全信息發(fā)布都有積極的意義。文中根據(jù)道路行車(chē)安全分析理論及空氣動(dòng)力學(xué)理論,充分考慮大、小型車(chē)對(duì)橫風(fēng)的安全敏感閾值存在差異,分別建立不同條件下的安全限速模型,并通過(guò)Carsim/Trucksim等軟件對(duì)模型計(jì)算結(jié)果進(jìn)行仿真分析,以保證所建模型能夠較為準(zhǔn)確地反映橫風(fēng)作用下的汽車(chē)動(dòng)態(tài),最終能夠較好地服務(wù)于橫風(fēng)行車(chē)安全預(yù)警系統(tǒng)。
[Abstract]:In highway wind-prone areas, it is easy to threaten the safety of vehicles because of the characteristics of sudden and concealment, and often lead to malignant traffic accidents. At present, there are few researches on the speed limit of cross wind multi-section vehicles in our country, so it is difficult to meet the safety requirement of cross wind weather. In addition, the anti-wind ability of different vehicles is very different under the action of crosswind. If the speed limit of large and small vehicles can be distinguished, it will be of positive significance to traffic management and safety information release. According to the theory of road safety analysis and aerodynamics, the safety sensitivity threshold of large and small vehicles to crosswind is considered in this paper, and the safety limit models under different conditions are established respectively. The simulation results of the model are analyzed by Carsim/Trucksim and other software to ensure that the model can accurately reflect the vehicle dynamics under the action of cross-wind, and finally serve the safety warning system of cross-wind vehicle better.
