摘　　要：锂电池切片机曲柄切刀机构是切片过程中的核心部件,其受力与运动直接影响片材切断面的质量。传统动力学方程推导复杂且设计周期长,为提高设计效率,采用虚拟样机进行动力学分析。首先,对锂电池切片机曲柄切刀机构进行机械建模,采用Newton-Euler法推导运动学方程,运用MATLAB进行理论分析。随后,在ADAMS软件中进行动力学仿真分析,结果表明仿真能准确拟合运动情况。结合有限元分析与σ-N特性曲线,验证曲柄的静强度与疲劳强度,发挥仿真技术的优势,对连杆构件进行优化设计。实验验证表明,动力学分析可有效获取机构运动特性及大量力学参数,优化后的机构可有效地减少工作过程中的振动力,强度校核方法可行,缩短了设计周期,提升了效率,为样机开发提供有效参考。The crank cutting mechanism of the lithium battery slicer serves as a pivotal component in the slicing process,with its force distribution and motion directly influencing the quality of the cut material's cross-section.Traditional derivation of dynamic equations can be complex and time-consuming,prolonging the design cycle.To enhance design efficiency,this study employs virtual prototyping for dynamic analysis.Initially,a mechanical model of the lithium battery slicer's crank cutting mechanism is developed.Newton-Euler method is then utilized to derive the kinematic equations,followed by theoretical analysis using MATLAB.Subsequently,dynamic simulation analysis is conducted in ADAMS software,revealing that the simulation accurately replicates the motion patterns.By combining finite element analysis with theσ-N characteristic curve,the static and fatigue strengths of the crank are validated.And give full play to the advantages of simulation technology to optimize the design of connecting rod components.The experimental verification shows that the dynamic analysis can effectively obtain the motion characteristics and a large number of mechanical parameters of the mechanism,and the optimized mechanism can effectively reduce the shaking force during the working process.The strength checking method is feasible,which provides an effective reference for the development of the prototype,shortens the design cycle and improves the efficiency.
