Analysis of influence of parameters of adhesive connection structure of gyroscope float assembly on static and dynamic performances
In order to reduce the assembly stress in the adhesive connection structure of high precision gyroscope float assembly and ensure the structural stability,the influence of the adhesive connection structural parameters on its static and dynamic properties was studied.The finite element model of the adhesive connection structure of the gyroscope float assembly was developed,and the uniformity of shear stress distribution and natural frequency were used to characterize the static and dynamic properties of the adhesive connection structure,and the influences of the adhesive layer thickness,adhesive layer length,buoy thickness and the adhesive layer shape on the static and dynamic properties of the structure were studied.The results showed that increasing the thickness and length of adhesive layer in a certain range and adopting parabolic adhesive layer could help to enlarge the advantageous bearing area of adhesive layer and improve the uniformity of stress distribution effectively.Additionally,reasonable increase of buoy thickness would decrease the first six natural frequencies of the adhesive connection structure with a greater reduction in higher orders.Conversely,the adhesive layer thickness had little influence on the dynamic property of adhesive connection structure.The research results have a certain guiding significance for the design and research of gyroscope components.
