| Abstract: | The mechanics model of a closed and O-shaped MEMS planar microspring was established and the calculation formula for the spring constant of the planar microspring was derived by Card's second law and Hooke's law.The results of the ANSYS finite element simulation show that their relative errors are below 2%.On the basis of the calculation formula and the simulation,the effect conditions of various structural parameters on the spring constant were researched.The results indicate that the spring constant decre... |
