摘要:
从汽车行驶理论入手,以解放CA141载重车为标准车型,对汽车的动力性及车辆在道路上的受力情况、运动方程进行分析,并充分考虑汽车在上下坡所受到的诸如空气阻力、海拔高度及车辆载荷等各种影响因素,探讨了山区公路最大坡长限制的确定方法.以分析结果为基础,提出我国<公路工程技术标准>应适当放宽最大坡长限制的建议,同时给出了山区公路最大坡长限制的修改建议值(并通过试验验证了分析的正确性),以供设计人员在设计过程中参考.
Abstract:
Starting from the automobile driving theory, taking the Jiefang CA141 truck as the standard model, the dynamic nature of the car, the force and motion equation of the vehicle on the road are analyzed, and the various influencing factors such as air resistance, altitude and vehicle load are fully considered when the car is exposed to the uphill and downhill, and the method of determining the maximum slope length limit of mountain roads is discussed. Based on the analysis results, the suggestions that the maximum slope length limit should be appropriately relaxed > the technical standards of China’s < highway engineering are put forward, and the recommended value for modifying the maximum slope length limit of mountain roads is given (and the correctness of the analysis is verified by experiments) for designers to refer to in the design process.
