摘　　要：为实现对摆式隔/减振系统摆线长度的微应变控制,继而为摆式隔振系统隔振一体化奠定基础,基于超磁致伸缩材料(GMM)设计了复合石英摆线。该复合摆线将GMM的磁致伸缩应变转换成轴向应力施加于摆丝上,使摆丝发生轴向形变。提出了磁控溅射镀膜与复合粘贴两种制备复合摆线的方法,并对比分析了复合石英摆线在磁场作用下的应变机理和应变特性。To achieve the micro-strain control of the cycloid length in the pendulum vibration isolation system,a composite quartz cycloid is designed based on giant magnetostrictive material(GMM),which provides the basis for the integration of the pendulum vibration isolation system.The composite cycloid converts the magnetostrictive strain of GMM into axial stress applied to the quartz cycloid,which causes axial deformation.In this paper,two methods of preparing the composite cycloid,magnetron sputtering coating and composite bonding,are proposed,and the strain mechanism and characteristics of the composite quartz cycloid under the action of magnetic field are compared and analyzed.
