摘要:
针对胶印机结构复杂的特点,提出基于虚拟试验获得胶印机整机性能数据的方法.以SolidWorks,COSMOS/Motion和ADAMS为虚拟样机建模平台,构建了某型胶印机印刷色组的虚拟样机模型.在ADAMS中对胶印机虚拟样机进行虚拟试验,获得了胶印机整机的静力学、运动学和动力学仿真数据.通过对虚拟试验数据的分析,明确了该型胶印机振动的主要来源及激振力的时域、频域特征,为胶印机的动态优化提供了参考.为了进一步降低串墨机构给整机带来的振动,进行了以4个串墨辊串墨运动初始相位为因素的试验设计,优选出了一组最佳的串墨初始相位搭配方案,基本上消除了串墨运动对整机的影响,取得了较好的优化效果.
Abstract:
Taking the structural complexity of offset press into account, an approach of obtaining machine performance data by virtual experiments is presented. With SolidWorks, COSMOS/Motion and ADAMS as modeling platform, the virtual prototyping for individual printing unit of an offset press was constructed. The virtual experiments toward the virtual prototyping were performed in ADAMS, and the statics, kinematics and dynamics properties of the machine were obtained. Through the analysis of simulation results, the major source of the machine vibration was found out, and the characteristics of the exciting force in time and frequency domain were revealed as well, which directed following dynamic optimization of the offset press. Furthermore, in order to reduce the vibration from the ink vibrating mechanism, the design of experiments toward the initial ink vibrating phase angles of the ink vibrators was carried out, and the optimal solution was selected as the ultimate design plan. As a result, the exciting force from the ink vibrating mechanism is basically eliminated, which shows that our optimization is effective.
