考虑轮胎侧偏特性的赛车转向几何研究
Study on Steering Geometry of Racing Cars with Consideration of Tire Cornering Characteristics
摘要
Abstract
For improving the tire lateral resultant forces and lateral accelerations of racing cars,a steering geometry was proposed considering the effects of tire cornering characteristics.The instanta-neous center of steering was defined by analyzing the impacts of tire slip angles,and a 3-DOF full ve-hicle model containing tire model was developed for steering simulation.The steering geometry was obtained via optimization of maximizing lateral resultant forces of tires by IP GA.Simulations and tests were conducted to validate the theoretical basis of the present steering geometry.The results in-dicate that the maximum lateral resultant force is raised under the design using the present steering geometry compared with Ackerman steering geometry.Thus the steering performance within extreme condition could be improved.关键词
