基于正交试验设计的轮胎湿路面附着性能优化研究

采用制动过程离散化分析方法，建立205/55R16子午线轮胎湿路面制动的有限元模型。以80～20 km·h^-1速度范围内的平均减速度作为评价指标，结合正交试验与有限元仿真，通过少量的运算次数，找出对轮胎湿路面附着性能影响的显著因素，从而对胎面结构进行优化设计，提高轮胎的湿路面制动性能。;Based on discretization analysis method of the braking process，the finite element model about the braking process of 205/55R16 radial tire on wet road was established.Taking the average braking deceleration between 80 and 20 km·h^-1 as evaluation index，combining orthogonal experimental design and finite element simulation，the significant influencing factors on the wet grip performance of tires were identified through only rather few experiments，and the tread pattern design was optimized to enhance the wet breaking performance of tires
