What is An Effective Pseudo-rigid-body Method for Beam-based Compliant Mechanisms about?

Beam-based compliant mechanisms have been widely used in many precision applications due to their large-displacement characteristic. Meanwhile, a simple and accurate analytical tool is no doubt useful to assist design and optimize these mechanisms. The pseudo-rigid-body (PRB) model is such a good alternative. The PRB model in a traditional sense, however, is too approximate to calculate some precise characteristics such as center-shift of a flexural joint. In this paper, a new method is proposed to easily establish simple and accurate PRB models for a variety of beam-based compliant mechanisms. As is well known, for most of the beam-based compliant mechanisms, there is usually an instantaneous center of rotation (ICR) on each beam, and the beam can be considered as a fixed-guided beam with one end fixed while the other end moves along a certain curve that usually is an approximate arc around the ICR. In this case, the behavior of beams can be imitated by a rigid bar with two pin-joints. One of the pin-joints is directly added at the end of the rigid bar. The position of the other is determined by the characteristic radius factor, and a torsional spring is added at the position to r
