Conceptual Design of 2-DOF Flexure-Based Sensing Mechanisms for Superconductor Gravity Gradient
View through CrossRef
By employing screw theory and the freedom and constraint topology (FACT), the type synthesis for 2-DOF flexure-based sensing mechanism of superconductor gravity gradient was produced with the parameterized compliance approach. Six types of mechanism with 1R1T DOF were deduced with freedom and constraint pattern in parallel topologies. Based on the compliance analysis, one type was selected as preferred sensing mechanism with the comparison of freedom, main direction compliance, parasitic errors, precision and complexity. For reducing the parasitic and coupling errors, optimization was produced with the parameterized compliance approach. Then specific geometric properties were presented with compact structure for the measurement application. The simulations showed the results of analytical models were close to that of FEA (finite elements analysis) models and the maximum errors of compliance parameters were less than 6%. The conceptual design of 2-DOF flexure-based sensing mechanisms could reach the required functions.
