In order to obtain the optimal structural parameters of high strain sensitivity of smart tool holder
this paper takes the maximum axial strain sensitivity
axial stiffness and torsional stiffness of the tool holder as the optimization objectives
and takes the first natural frequency of the tool holder within the design requirements as the constraint condition
the approximate response surface model of optimization objectives was established based on the response surface method
and the relationship between design variables and optimization objectives was analyzed. The multi-objective optimization design of the smart tool holder structure was carried out by non-dominated sorting genetic algorithm-Ⅱ
and the Pareto optimal solution of smart tool holder structure parameters was obtained. Compared with the standard tool holder
the axial strain sensitivity of the optimized tool holder is increased by 32.8%
the axial stiffness is reduced by 14.8%
the torsional stiffness is reduced by 18.2%
and the first natural frequency is reduced by 10.1%.
