Abstract:三维椭圆振动辅助切削(EVAC)是一种具有广阔应用前景的加工方法,三维EVAC能否在实际加工中表现出最佳性能,取决于三维EVAC装置的性能。目前已研制的三维EVAC装置存在产生椭圆轨迹形式单一、椭圆轨迹范围可调性差等问题,为此,本文对多种椭圆振动轨迹并存的三维EVAC装置进行了研究,从装置布局和尺寸优化方面探索了所设计装置的性能优化方法。首先采用三个相互垂直且结构形式相同的子链和柔性铰链放大结构的形式进行三维EVAC装置的设计,输出轨迹可调的三维椭圆振动,分析了产生三维椭圆振动轨迹;其次运用有限元方法对设计的装置进行了静力校核和动力瞬态分析,验证了刀尖轨迹多种输出方式;最后根据有限元分析的结果,从布局和尺寸方面建立三维EVAC装置的柔性铰链优化模型,对设计装置的尺寸参数和结构布局参数进行了分析和优化,得到装置最优参数。
