| Abstract: | A kind of new typed micro-displacement amplification mechanism was designed according to the amplification principle of differential lever displacement.The displacement amplification multiple and static rigidity of this displacement amplification mechanism were calculated and derived,and the influences of flexible hinged structural parameters on the rigidity of micro-displacement amplification mechanism were analyzed.A contrast was made on the theoretical caleulation result with the ANSYS simulation result which indicated that there existed certain differences between the value of theoretical computation and the result of finite element simulation. |
