摘要
在弹性胎面和刚性胎体假设的基础上 ,分析了非稳态条件下印迹侧向变形的几何关系和印迹侧向“入口 /附着”条件。根据非稳态侧偏刷子模型和不同侧向输入间的几何关系 ,进一步分析了轮胎非稳态转偏刷子模型的建模机理 ,并推导出稳态转偏刷子模型。还分析了轮胎侧倾滚动时侧向变形以及轮胎滚动半径与垂直变形随横向坐标的变化关系 ,讨论了考虑胎宽时轮胎稳态侧倾刷子模型的建模过程。
The geometric relations of lateral deformation and “entry/adhesion” condition of contact patch in non steady state conditions were analyzed based on the assumption of flexible tread and rigid carcass. Modelling mechanisms of the tire turn slip brush models were further analyzed according to non steady state tire cornering brush model and the geometric relations between two groups of different lateral inputs. The steady state turn slip brush model was then derived. Lateral deformation and the variations of rolling radius and vertical deformation versus transverse axis were also analyzed when a tire was rolling in camber state and modelling process was then discussed about tire camber brush models considering tire width in steady state conditions.
