摘要
利用优化设计和ADAMS运动仿真技术,优化了牛头刨床六杆机构,改善了其综合性能,设计过程实现了机构设计的形象化和最优化的统一。首先利用矢量解析法对六杆机构进行了运动学分析,然后建立了以刨头的工作速度平稳性为目标函数的优化设计数学模型,采用复合形法对其进行求解。最后利用ADAMS软件对优化后的机构进行了仿真,结果表明,优化后的六杆机构中,刨头在工作行程中的速度平稳性得到了明显改善,加速度峰值减小了39.17%,空行程时间缩短了41.67%,由此可以提高刨削效率和质量。
Optimization and ADAMS simulation technology are integrated to improve the comprehensive perfor- mance of six - bar mechanism of shaper, and this method unites the visual simulation process with the optimized result perfectly. At first, the kinematic analysis of six - bar mechanism of shaper is conducted with the vector analytic method. Then, the mathematical model of optimization is established to aim at stationarity of working speed of plough head, and the optimization process uses the complex - shape method. At last, a simulation for the optimized six - bar mechanism is performed with ADAMS. The results show that the performances of plough head is improved evidently： the maximum of acceleration is reduced by 39.17%, the non- working stroke is shortened by 41.67%. The cutting efficiency and surface quality are improved.
