| Abstract: |
| In the following-up support machining of thin-walled parts,the positioning layout of the support head has a significant impact on the vibration damping effect.Based on the whiffletree layout strategy and the coupled tool-workpiece-support vibration model,this paper establishes a layout optimization model with the number of support points and the support radius as decision variables.The optimization indicators are the amplitude and root mean square of vibration magnitudes,and the variable range is established through structural interference and boundary conditions.Furthermore,to address in differential equations constraints,inequality constraints,and mixed-integer problems in this optimization model,a composite search strategy is formulated,primarily using the particle swarm algorithm supplemented by parameter scanning and penalty functions.Finally,the efficiency and feasibility of this search strategy are verified through simulations,and the optimal layout parameters for the given case are obtained.This optimization model and search strategy can provide insights for similar layout optimization problems in other physical systems. |
