摘　　要：超磁致伸缩材料和压电材料在商业产品和军事领域中被广泛应用。尽管这些材料具有输出力大、频响高等优点,其应用依然受制于其输出位移小的问题。使用机械放大机构是解决这一问题的有效途径。研究主要的3种基于超磁致伸缩材料及压电材料的机械放大机构,得出铰链式位移放大机构较适用于压电材料,液压位移放大机构适用于微机电系统而压曲放大机构适用于超磁致伸缩材料的结论。Giant magnetostrictive materials （GMM） and piezoelectric （PZT） materials have been significantly used in commercial products as well as military applications, with high energy density, long life, and electric drive advantages. Although these materials have high force and large bandwidth capabilities, their use has been limited due to their small stroke. The use of mechanical amplifiers is an effective way to overcome this problem. This article will review recent literatures of three main kinds of design methodologies of mechanical amplifiers for GMM and PZT materials. It is proposed that the flexure-hinged displacement amplifiers, Hydraulic displacement amplifiers and Flexural frame displacement amplifiers are suitable for piezoelectric materials, miro-electro-mechanical systems and Giant Magnetostrictive materials, respectively.
