摘　　要：分析了发动机配气机构凸轮型线设计要求和型线选择,建立了凸轮型线多目标优化数学模型,基于Matlab软件编制了凸轮型线进行多目标优化设计的程序。给出了计算实例,实例表明通过优化改善了挺柱运动的平滑性,提高了配气机构的性能。The design requirement of cam profile of the valve train of V - type engine, and selection of cam pro- file are analyzed, the multi - objective optimization mathematical model is built. Based on Matlab software, the pro- gram is also compiled for multi - objective optimization design of cam profile. An example is given and results show that the smoothness of tappet movement and the performance of valve train are improved by the optimization.
