【摘要】：当前，我国经济社会快速发展，公路建设形势如火如荼，汽车保有量与日俱增，人们选择公路交通作为出行方式的频率越来越高，出行范围也越来越广。随之而来的是，人们对公路交通的要求也在不断的变化和提高，不仅仅再局限于安全、高速、便捷、通达等方面，舒适逐渐为评价公路出行质量的重要指标，受到人们越来越多的关注。驾乘人员的舒适体验不仅受到汽车方面因素的影响，而且与公路线形质量有着密不可分的关系。公路平、纵线形参数与驾乘舒适度相互影响，相互促进。鉴于此，提出了驾乘舒适度与公路平、纵线形参数之间的关系研究课题，，具有一定的理论价值和现实意义。本文首先介绍了国内外公路线形参数研究现状和发展概况。结合驾乘舒适度的相关理论，阐述了驾乘舒适度的内涵，总结分析了影响驾乘舒适度的因素，其中公路线形质量决定了公路的平顺性，也是最为重要的影响因素。在此基础上，重点定性地研究了驾乘舒适度与公路线形参数的相互影响关系。接着，从汽车和道路两个不同角度，研究了国内外出现过的驾乘舒适度评价指标和评价方法，通过分析比较两角度之间的联系和各方法的适用条件，研究论证了ISO2631国际标准是适用于我国公路线形研究的评价标准，并确立加速度为联系公路线形参数和驾乘舒适度之间的纽带。最后，通过分析汽车行驶过程中的驱动力和各种阻力导出运动方程式，研究探讨了行驶在曲线路段上车辆的受力平衡，找出了公路平、纵线形参数与驾乘舒适度之间的量化关系，并得到量化公式。基于量化公式，计算得到考虑驾乘舒适度的公路平纵线形参数的推荐值。借鉴ISO2631国际标准，运用VisualBasic6.0软件编写了驾乘舒适度综合评价程序，对某二级公路路段的驾乘舒适度进行分析评价，得出评价结果进一步验证了该方法的可行性和实用性。本文的研究价值在于利用研究成果不仅可以评价已建公路的驾乘舒适度，还可以用来指导公路路线设计工作，为公路线形设计提供有益参考，具有一定的实践性和创新性。
[Abstract]:At present, with the rapid development of our country's economy and society, the situation of highway construction is in full swing, the number of cars is increasing day by day, people choose road traffic as the travel mode more and more frequently, and the travel range is becoming wider and wider. People's requirements for highway traffic are also constantly changing and improving, not only limited to safety, high speed, convenience, accessibility and other aspects, comfort is gradually an important index to evaluate the quality of road travel. People pay more and more attention to it. The comfortable experience of drivers is not only influenced by the factors of automobile, but also closely related to the quality of highway alignment. In view of this, the research on the relationship between the driving comfort degree and the horizontal and longitudinal parameters of the highway is put forward, which has certain theoretical value and practical significance. This paper first introduces the research status and development of highway alignment parameters at home and abroad. Combined with the related theory of driving comfort, this paper expounds the connotation of driving comfort, summarizes and analyzes the factors that affect the driving comfort. The quality of highway alignment determines the smoothness of highway and is also the most important factor. On this basis, the relationship between driving comfort and highway alignment parameters is studied qualitatively and qualitatively. Then, from two different angles of automobile and road, this paper studies the evaluation index and evaluation method of driving comfort degree which has appeared at home and abroad, and through the analysis and comparison of the relationship between the two angles and the applicable conditions of each method, It is demonstrated that ISO2631 international standard is suitable for the study of highway alignment in China, and the acceleration is established as the link between highway alignment parameters and driving comfort. Finally, by analyzing the driving force and various kinds of resistance in the driving process of the vehicle, the equations of motion are derived, and the force balance of the vehicle driving on the curve section is studied, and the road level is found out. The relationship between the longitudinal profile parameters and the driving comfort degree is obtained, and the quantization formula is obtained. Based on the quantization formula, the recommended values of the highway horizontal and longitudinal line parameters considering the driving comfort degree are calculated, and the ISO2631 international standard is used for reference. The comprehensive evaluation program of driving comfort degree is compiled by using VisualBasic6.0 software to analyze and evaluate the driving comfort degree of a second class highway section. The evaluation results further verify the feasibility and practicability of the method. The research value of this paper is that using the research results can not only evaluate the driving comfort of the built highway, but also can be used to guide the highway route design, and provide a useful reference for the highway alignment design. It is practical and innovative.
