Collision Analysis and Optimization of the "Bench Loong" Model

The traditional folklore activity of Bench Loong is an excellent spectacle, but it is necessary to ensure that the loong can be freely coiled in and out to avoid collision. The extant theories are deficient in that they lack a mathematical analysis of the collision problem of the Bench Loong in motion. This paper presents a dynamic simulation of the basic motion process of the Bench Loong, followed by a geometric analysis of specific collision scenarios based on the shape of the bench and the motion process. This analysis leads to the establishment of a collision analysis criterion, which is then applied to the specific process of the Bench Loong to determine its termination time and state. Although the model is idealized to a certain extent, it is nevertheless highly accurate and provides a reference for the design of the coiling path of the Bench Loong, which is of great value and significance for the inheritance and promotion of traditional culture.
