摘要
高速精密数控冲床导轨可靠性关系到整机的动态精度和加工质量,通过对高速冲床传动系统曲柄滑块机构进行运动学分析,同时运用SOLIDWORKS软件建立机构的简化模型,并导入ADAMS软件中施加约束、驱动和冲击载荷,然后进行运动学仿真验证计算的准确性;再运用ANSYS软件对导轨进行柔性体转换,之S后对曲柄滑块机构进行柔性体动力学仿真,获取导轨在实际加工过程中的载荷谱、实体应力分布和柔性变形量,为机床可靠性设计分析和寿命预测的准确性提供了必要的基础。
The reliability of high-speed punch guide can directly affect the dynamic accuracy and processing quality of punching machine.Through the kinematics analysis and kinematic simulation of slider-crank mechanism,by building a simplified model of the mechanism with SOLIDWORKS software,and importing into ADAMS software to constraints,drive and punching load,the dynamic simulation is made to verify the correctness of the calculation.Then by applying ANSYS software flexible body converting for the rigid guide is done,and dynamics simulation for slider-crank mechanism is carried out to acquire the load spectrum,stress distribution of the entity as well as and flexible deformation in the actual processing,which provides necessary foundation for the accuracy of reliability analysis and life prediction.
