Topology Optimization of Headstock of Heavy Machine Tool
The problem of topology optimization of large spindle box of heavy machine was studied. Based on ICM topology optimization, the parameters topology optimization were changed by sensitivity analysis and the sensitivity parameters were normalized; the topological parameters were modified and removed which judgment based on the sensitivity of the cross-section unit cell in the progress of optimization. Example shown that the integrated optimization method made the structure optimization more intuitive, not only avoided effectively the occurrence of the load strange in the optimization process, but accelerated the convergence speed.
