Abstract

The dynamics of the 1.5-degree-of-freedom model of towed wheel is investigated. Dry friction at the king pin is considered, leading to a non-smooth dynamical system. Beyond analytical and numerical linear stability analysis, the nonlinear vibrations are investigated by numerical bifurcation analysis with smoothing and by numerical simulations with event handling. The effect of dry friction at the king pin on the birth of separated periodic branches is presented on bifurcation diagrams. The presence of bistable parameter domains is also shown. The effect of smoothing is investigated by comparing bifurcation diagrams of the smoothed and the original non-smooth systems.

带干摩擦减振器的摆振车轮数值分析

研究了1.5自由度拖轮模型的动力学特性。考虑主销处的干摩擦，导致动力系统非光滑。除了解析和数值线性稳定性分析外，还通过光滑的数值分岔分析和事件处理的数值模拟来研究非线性振动。在分岔图上给出了主销处干摩擦对分离周期分支生成的影响。双稳参数域的存在也得到了证明。通过比较光滑系统和原始非光滑系统的分岔图，研究了光滑的效果。
