Abstract

Abstract The article concerns the problem of lateral stabilization of a tricycle with variable front wheel track. The vehicle can operate in two modes: with the front wheels folded out and connected. A bicycle designed for people with special needs. The element that requires elaboration is the stabilization while driving with the front wheels unfolded. In this mode, a metastable state is created. When the lateral angle of the slope exceeds the limit value, the lateral force causes the lateral tilt. This phenomenon should be treated as a disadvantage as it makes it difficult to smoothly tilt the bicycle, which can lead to disorientation of the rider and difficulty in maintaining balance. The article presents mathematical simulations that allow for the analysis of factors influencing the discussed phenomenon.

可变前轮间距三轮自行车的亚稳态条件

摘要本文研究了具有可变前轮轨迹的三轮车的横向稳定问题。该车可以在两种模式下运行:前轮折叠并连接。为有特殊需要的人设计的自行车。需要详细说明的因素是稳定驾驶时，前轮展开。在这种模式下，会产生亚稳态。当边坡的侧向角超过极限值时，侧向力会引起侧向倾斜。这种现象应该被视为一种缺点，因为它使自行车难以平稳倾斜，这可能导致骑自行车的人迷失方向，难以保持平衡。本文提出了数学模拟，以便分析影响所讨论现象的因素。

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.
