| 摘 要： | 在现代发动机开发过程中,CAE软件的应用已经成为降低开发成本和缩短开发周期的主要手段.针对某微小型汽车发动机性能提升的改进工作,利用AVL Excite Timing Drive软件对发动机凸轮轴型线进行优化设计.建立了该发动机的单阀系统模型,在给定的配气机构零件基础上利用多段函数的数学方式优化了凸轮轴的缓冲段和工作段型线.优化后的结果表明,采用梯形函数形式的缓冲段,以及分段函数形式的工作段的凸轮轴型线,既能满足配气机构的动力学和运动学要求,同时达到了提高发动机中低速扭矩的性能目标,有效降低了整机的开发成本和周期.

| Abstract: | Cam profile is optimized with AVL Excite Timing Drive.The model of engine sigle valve is built,using functional equation to optimize the profiles which indicate cushion area and operation area is carried out for assigned valve train components.The profiles in cushion area and operation area meet the requirements in dynamics and kinematice,the engine performance in low and medium speed ranges is improve as well,the development cost and development time are significantly reduced. |
