摘要

这项研究提出了一种参数缩放方法，用于极端机动情况下的尺寸分析。使用尺寸分析法进行缩放车辆实验在测试位置、驾驶员安全和节约成本方面具有优势。以往的研究忽视了轮胎在尺寸分析中的非线性效应。本文介绍了两种方法：对轮胎和表面之间的摩擦系数进行缩放，以及通过时间缩放对重力加速度进行虚拟缩放。使用 1/8 比例车辆和 CarSim 软件程序对这两种方法进行了验证。这项研究为车辆动力学中的参数缩放建立了一种实用有效的方法，同时考虑到了轮胎的非线性和极端机动性。

Dimensional Analysis of Ground Vehicle in Extreme Maneuver Scenarios

This research proposes a parameter scaling method for dimensional analysis in extreme maneuver scenarios. Scaled vehicle experiments using dimensional analysis offer advantages in terms of test location, driver safety, and cost savings. Previous studies have overlooked the nonlinear effects of tires in dimensional analysis. Two methods are presented: scaling the frictional coefficient between tires and surfaces and virtual scaling of gravitational acceleration through time scaling. The methods were validated using a 1/8 scaled vehicle and the CarSim software program. This research establishes a practical and valid approach to parameter scaling in vehicle dynamics, considering tire nonlinearity and accommodating extreme maneuvers.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
