摘要
为了提升营运车辆安全性能,有效遏制和减少因车辆主动安全性能不足导致的道路运输事故,中华人民共和国交通运输部于2018年2月26日发布行业标准JT/T 1178.1-2018《营运货车安全技术条件第1部分:载货汽车》,标准中第4.9项要求:载货汽车在空载状态下按照附录B规定的试验方法进行试验,转弯通道最大宽度应小于等于5.0m。本文以标准中附录B《车辆直角弯道通过性试验方法》为基础,根据汽车转向原理,利用数学建模的方式,研究载货车直角弯道通过性仿真的方法。最后,利用Visual Basic语言设计程序对载货车直角弯道通过性进行仿真,并将仿真结果与试验结果进行比较,结果表明该仿真方法是有效的。
In order to improve the safety performance of operating vehicles and effectively curb and reduce road transport accidents caused by Active safety performance of vehicles,the Ministry of transport of the people's Republic of China issued the industry standard JT/T 1178.1-2018 Technical Conditions for Operating Trucks'Safety Part 1:Trucks on February 26,2018.In which item 4.9 requests:the truck shall be tested in no-load state according to the test method specified in Appendix B,and the maximum width of turming channel shall be less than or equal to 5.0m.On the basis of Appendix B of the standard,Test Method of Passing Through Right Angle Bend of Vehicle,according to the principle of vehicle steering,using the method of mathematical modeling,this paper studies the simulation mcthod of passing through right anglc bend of truck.Finally,using Visual Basic programming language to simulate the right angle bend trafficability of the truck,and by comparing the simulation results with the test results,the results show that the simulation method is effective.
