Cold roll-beating is a new advanced plastic forming technology, obtaining the forming force varying law is key to study the forming mechanism. Aiming at force measuring requirement in cold roll-beating forming process and the forming principle, a strain gage type dynamometer dedicated for cold roll-beating was designed, and a new type of elastomeric structure was proposed. ABAQUS software was used to simulate the static and dynamic characteristics of the structure, then the strain distribution rule of the elastomer surface sensitive position and the harmonic response characteristics and dynamic sensitivity of each gauging point were studied. Finally, experiment were carried out to calibrate the design dynamometer) and the results show that the dynamometer is suitable for measuring the cold roll-beating forming force.
