Optimization Design of the Four-Sided Planer Body for Glued Laminated Curved Beams Based on the SIMP Method
To ensure the machining accuracy of the four-sided planer,the structural design of the machine body should aim to minimize mass,reduce stress deformation,and increase stiffness and natural frequency.Based on the SIMP method,a topology optimization mathematical model is established with the machine body mass as the optimi-zation objective and stress deformation and natural frequency as constraints.After achieving topology optimization,a statics and modal analysis is performed on the reconstructed model.Subsequently,the model undergoes a second re-construction,followed by response surface dimension optimization,resulting in the final machine body structure mod-el.The results show that after optimization,the machine body mass decreased from 1880 kg to 1068 kg,the maxi-mum deformation reduced by 23.39％,the maximum stress value decreased by 32.06％,the first natural frequency increased by 10.04％,and the second natural frequency increased by 3.34％,with varying degrees of improvement in the remaining top six frequencies.
