摘要
压电驱动器的位移输出能力有限,通常借助于柔性机构对其位移量进行放大。提出一种柔性八杆放大机构,并对 其进行有限元分析和理论计算。为了提高放大率,提出两级串连式机构。机构整体具有结构紧凑、放大效率较高的优点。
Piezoelectric actuator can provide only limited displacements,thus a compliant mechanism is usually used to make those actuators efficient.Compares and analyses the performance of a few kinds of compliant amplification mechanism,and a 8-links compliant amplification mechanism is introduced and built.Finite element analysis and theory calculation is also presented.To achieve more displacement gain,a two-mechanisms in series is recommended.The mechanism is compact and can get more amplification gain.
