Bionic and Reconfigurable Force Amplifiers Based on the Length and Angle Effect of Bars

Abstract:

Observation of the present force amplification mechanism suggests geometrically simple bars have length effect and angle effect, both contributing to the amplification of force. Those bars are prevalent in animal bone structures. A set of design methodology and principles of reconfigurable force amplification mechanism is presented based on bionics. Following a few basic rules, engineers could use bars to construct innovative structures with various functions to meet practical requirements. Some example cases are displayed along with related equations. The effects of lever and toggle mechanism in series are compared to that of ordinary systems. The former displays remarkable advantages.
