摘要：

A double-drive feed system has the characteristics of complex loads and multi-thermal sources, so the dynamic performance of the feed system is a thermal-mechanical coupling problem. In this paper, the mechanism of the thermal-mechanical coupling effect on the vibration of the machine tool feed system is discussed. The effect of the thermal-mechanical coupling effect on the dynamic performance of the feed system was analyzed by experimental data, as well as the influence of the coupling effect on the structural deformation. The above results showed that a rising temperature made the natural frequency of the system decrease and the vibration amplitude of the feed system increase with a maximum rate of increase up to 14.06 %. Through experiment and simulation, the dynamic simulation and analysis method of the thermal-mechanical coupling of a machine tool feed system are shown to be rational and feasible.
