Robust optimization design of flexible hinge flexibility based on Taguchi method

The flexibility robustness of compliant mechanism is the premise of compliant mechanism widely applying in miniature electromechanical systems and precise engineering field.In practice,this problem cannot be solved by using traditional method.A new robust design method was presented,the structural parameters of flexure hinge and working load were selected as well.By processing and analyzing test data resulted from orthogonal test,the best combination of parameters was obtained and verified by experiment.The results demonstrated that,against the traditional design,the signal noise ratio increased about 4.68 dB,the quantity loss of flexible hinge reduced.It also implemented the flexibility stability optimization on the flexible hinge.Finally,the flexibility robustness of flexible hinge could be optimized.The robust design can be widely used and has reference value in application.
