Structral Design And Dynamic Analysis Of The Two-Axis Turntable

Table is a tracking test system main device, Are widely used in the field of aerospace, aviation, marine detection, atmospheric channel wireless laser in military and civil fields. In addition, the structure design of the pedestal will directly affect the working turntable tracking accuracy, Which affects the working performance of the final system, Based on a practical laser communication engineering project as the background, designed the overall structure and dynamics analysis table.According to the technical index, The overall design of the platform, designed to meet the requirements of the "U-O" type two axis turntable. According to the theory of finite element, Finite element analysis with ANSYS software foundation, The mechanical structure of two axis simulator on the mechanical analysis, Get the turntable stress deformation and displacement of turntable by statics calculation, The two axis table basically meet the requirements of strength and stiffness; Through the modal analysis, get the vibration frequency, amplitude and the vibration type image corresponding to the structure design, the frequency response is not resonance occurs, can ensure that the turntable tracking accuracy.Finally, according to the results of the analysis of static, dynamic, The two axis turntable mechanical structure design, the initial scheme of the practicability of frame, frame and the base structure improvement. And the improved scheme is analyzed and calculated, ensure that the improved structure meets the requirements of static and dynamic characteristics of the turntable, also related to the future design of two axis turntable provides useful tools and effective reference.
