Dynamic optimization design of a high-speed and high-precision HMC

In the dynamic design of a high speed and high precision horizontal machining center(HMC),the contact parameters of guide surfaces were acquired by dynamic tests and applied to the numerical simulation model to improve its accuracy.Based on independent continuous mapping(ICM) topology optimization theory,a new topology optimization method considering undesigning aggregates was put forward in structural optimization design of a machining center,and applied to design of the main parts to improve both the static and dynamic properties of the machining center.To unavoidable resonance problems in machining,using machine-tool accessories,a tuned-damper was designed to suppress vibration of machines.
