英文摘要	Here, a planar flexible hinge was proposed to realize functions of Hook hinge. Based on the analysis of DOFs of this flexible hinge, its motion forms were extended. The theoretical model to calculate its dynamic equivalent stiffness was established for two poses of the hinge. The nonlinear variation law of the stiffness under large deformation pose was explored with Gaussian fitting method. The correctness of the model was verified on the finite element platform. According to the theoretical model, variation features of the whole hinge stiffness were analyzed, and the hinge performance characteristics were explored. Finally, the planar flexible hinge was introduced into a 6-DOF parallel vibration isolation platform. The rigid-flexible coupled dynamic analysis of the new platform was conducted using ADAMS and ANSYS combined simulation. The results showed that the proposed planar flexible hinge can meet requirements of Hooke hinge motions, and at the same time it can effectively avoid abrupt change problems of the vibration transmissibility caused by Hooke hinge gap. © 2019, Editorial Office of Journal of Vibration and Shock.
