| 目的 为了提高食用菌培养基包装机抱合机构的运动平稳性， 改善机构的传力性能。方法在 ADAMS 环境中进行参数化建模、 机构动力学仿真和综合优化设计。在优化设计数学模型中， 将支承轴最大横向反力 FOx max， FJx max和抱合块最大加速度 apis max纳入多目标的设计评价函数， 将活动构件之间的运动角作为优化设计的约束条件。通过仿真实验筛选出优质参数θ1和θ3， 并确定其合适的取值范围， 剔除低质参数。结果 进行对比性的动态综合优化， 选取针对对象与目标的优势参数组合（包含θ1和θ3的设计参数组合）具有优势； 综合动态优化使机构各支承轴上的最大反力下降了30%~40%， 末端构件抱合块的最大加速度下降了34.4%。结论 耦合效应会掩盖独立参数对仿真结果的影响， 设计软件应能进行单参数的独立调整， 以保证优化后规范的结构参数值能够直接进入工程应用。 |

| This research aimed at improving the stability of the packaging proper piece and the force transmission performance of packaging machine institutions of mushroom medium. The model of the machine was parameterized, simulated, and optimized in ADAMS. The maximum horizontal reaction force FOx max, FJx max and the maximum acceleration apis max of the packaging proper piece was included in the multi-objective design evaluation function in the optimal designed mathematical model, and the motion angles between components were taken into account as the constraint conditions of optimal design. In simulation, the highly sensitive θ1 and θ3 were chosen for optimization and their range were decided to eliminate low-quality parameters. By comparative and comprehensive dynamic optimization, it was advantageous to select a combination of superior parameters (including the combination of the design parameters θ1 and θ3) specific to objects and targets. The maximum reaction force on each support shaft was reduced by 30% ~40% and the maximum acceleration of the packaging proper piece was reduced by 34.4%. The simulation experiment showed the influence of the single parameter may be concealed by the coupling effect of the multi-parameter optimization. However, the CAE software allowed independent modification of single parameter, thus ensuring the standardized structure parameters to be directly applied to engineering. |
