摘要
为保证设计凸轮满足无菌灌装机高速状态下执行机构末端位姿高精度与运动稳定要求。基于谐波分析法对设计预成型凸轮机构末端在不同工作区段的动态响应进行校核;在ADAMS环境下对凸轮机构动态仿真得到执行机构末端夹爪的轨迹与机构在工作要求转速下的运动学与动力学特性曲线。结果发现,执行机构末端夹爪满足无明显振动响应要求;预成型凸轮连杆组合机构要求转速下凸轮与滚子能保持良好接触,摆臂的角加速度曲线平缓。
In order to ensure that the designed cam meets the requirements of high precision and stable motion of the end position of the actuator under the high speed state of the aseptic filling machine.Based on the harmonic analysis method,the dynamic response of the design of the pre-formed cam mechanism end in different working sections is checked.Under the ADAMS environment,the dynamic simulation of the cam mechanism obtains the trajectory of the end gripper of the actuator and the kinematics and dynamic characteristic curve of the mechanism at the working speed.The results show that the clamping jaws at the end of the actuator meet the requirements of no obvious vibration response;the pre-formed cam-link combination mechanism requires that the cam and the roller keep good contact at the speed,and the angular acceleration curve of the swing arm is gentle,which provides a basis for the actual use of the cam mechanism.
