The modal analysis and harmonic response analysis of the machine tool table with periodic truss-core structures are analyzed and calculated by finite element analysis software-ANSYS Workbench, then we get the finite element analysis results. After comparing the results with finite element analysis results of the original machine tool table, we come to the conclusion that the dynamic properties of the machine tool table with periodic truss-core structures are better than the original machine tool table’s. It makes a base for optimized design and remanufacturing.

This paper presents the optimized design and Finite Element Analysis (FEA) of a bio sensor based on cubic silicon carbide (3C-SiC) for pathogen detection. Silicon Carbide is chosen due to its excellent material properties and chemical stability compared to silicon in varying environmental conditions. The desired resonance frequency is optimized using matlab and the finite element analysis is carried out using COMSOL and Intellisuite software’s. The effect of the residual stress on the desired mode of resonant frequency and the fabrication feasibility of the proposed resonator fabrication are studied using FEA analysis. The mathematical modeling of thermally actuation and piezoresistive sensing for the design resonator bio sensors are illuminated. The close agreement between the analytical model and finite element analysis verify the design of proposed bio sensors.
