| Abstract | Based on the analysis of a 1.2m-diameter active primary mirror system under gravity load, several performance parameters of actuator are reported in this paper. The actuator is demanded to satisfy the active optics correction, support the axial load of primary mirror, and compensate the deformation of axial supports. The quasi-Zernike polynomials are employed to fit the maximal allowed surface error of telescope to compute the force accuracy of actuator. Moreover, the axial load and deformation of primary mirror system is analyzed by using the finite element (FE) method. Through the above procedures, the performance parameters, such as force range, force accuracy, axial stroke and displacement resolution, are obtained.; Based on the analysis of a 1.2m-diameter active primary mirror system under gravity load, several performance parameters of actuator are reported in this paper.
