Abstract
To reduce the processing cycle and cost of sheet metal parts, a flexible fixture is designed by light weight method. First, the finite element analysis techniques adopted are summarized. Second, the static and modal analysis of the flexible fixture unit is carried out to obtain the design structure that meets the strength and rigidity requirements. Third, the lightweight design of the base of the positioning clamping unit is carried out after the analysis of the design structure of the positioning clamping unit. The modal analysis results of the positioning clamping unit show that at the operating frequency of 50Hz, the positioning clamping unit designed in this research would not resonate. Lightweight design results obtain the optimal section design parameters, achieve the purpose of reducing the weight of the flexible fixture base structure, and save the cost. Therefore, the results of this study provide a good idea for flexible fixture to adapt to the diversity of mechanical products.
