摘要
运用禁忌搜索算法和Matlab语言,对内燃机配气凸轮机构的动力学数学模型进行了仿真优化计算,结果与原设计相比,丰满系数提高了1.2 4 % ,动态最大正加速度在上升段下降了0 .87% ,在下降段上升了5 .2 3% ,动态最大负加速度下降了5 .93% ,加速度变化趋于平稳。
Crash and noise in operation, dynamical optimization model regarding timing cam mechanism in internal combustion engine was built. Based on tabu search algorithms and Matlab, optimization simulation has been done. Compared with original design, the simulation results showed that plentiful coefficient increased by 1.24%, dynamical maximum positive acceleration lowered by 0.87% in ascending and increased by 5.23% in descending, the maximum negative acceleration decreased by 5.93%. The change of acceleration became more stable and the optimization effect was better than that of genetic algorithms.
