摘要
为了使干草压缩机构设计的更加合理,以干草压缩机六杆机构为例,对其进行了仿真和优化分析。首先,运用矢量解析法建立干草压缩机六杆机构的数学模型,再利用ADAMS软件建立干草压缩机六杆机构模型,并对机构进行运动学仿真分析,通过仿真直观揭示干草压缩机活塞的运动规律和状态。再把理论计算与仿真结果进行比较,验证仿真分析的正确性和可行性。最后,通过参数化建模,分析各杆长度变化对机构运动性能的影响,以获得最小加速度值为目标函数,实现了机构的优化设计。
At first,the mathematical model of the six-bar mechanism of a hay compressor was established with the vector analytic method.Then the geometrical model of the six-bar mechanism of the hay compressor was created by the simulation software ADAMS,and kinematics simulation analysis on the model was carried out.The simulation results reveal the movement regularity and state information of piston.By comparing the simulation results with theoretical calculation results,the validity of this model and its simulation results were verified.Finally,through the parameterized modeling,how the length change of each rod of the mechanism to affect its performance was analyzed.Taking the acceleration as optimization objective,the optimal design of mechanism was realized.
