基于一维纵向振动理论，利用理论解析法设计了机械微细加工辅助用振动平台。利用有限元软件进行优化设计，确定了圆锥段的最佳开槽数量和圆柱段的最佳开狭缝数量，改善了工作面的振幅分布均匀性，增大了工作面的振幅；增加圆锥段的长度以减小振动平台的谐振频率，通过有限元分析，研究了振动平台的谐振特性，满足工程应用的要求，验证了设计方法的可行性。为大尺寸振动体的设计提供了一种简便的方法。

On the basis of the theory of one‐dimensional longitudinal vibration ,ultrasonic vi‐bration system in ultrasonic vibration assisted micro machining was designed using the theoretical analytical method .The optimal solution about slot number of conical section and slit number of cylindrical section was determined by finite element software ,which improves the uniformity of amplitude in workplace and enlarges the amplitude in workplace .The resonant frequency of vi‐bration platform is reduced by increasing the length of conical section .The resonance characteris‐tic of the system was investigated by modal analysis with the finite element software ANSYS , which meets the engineering requirements and verifies the feasibility of the design method .The study provides a convenient way to design large sized vibrators .
