To improve the performance of the 2 m telescope,the optimum design is applied to the telescope assemble.Referring to the telescope assemble with the dimetric truss,a group of reasonable sizes of the telescope assemble are found by optimization methods and modal analysis,which will raise the resonant frequency by 4.21%.As a result,the telescope assemble is less likely to resonate.Besides,the dynamic response module in ANSYS is utilized to analyze the modal type,harmonic vibration response and random vibration response of the telescope assemble.By the calculation of ANSYS,finite element analysis (FEA) method proves that the performance of the telescope assemble is mildly enhanced by means of optimum design.
