ABSTRACT

This paper presents a method based on response surface methodology (RSM) to calculate the convective heat transfer coefficients (CHTCs) of a feed drive system. First, the temperature values at thermal-critical points and ball screw thermal elongation of a feed drive system were obtained by experimental and finite element (FE) methods. Second, the relationship between the CHTCs and simulated temperature values was established using RSM, and the CHTCs were calculated using the designed 25 tests. Finally, the effectiveness of the proposed method was proved using steady-state and transient-state simulation of the feed drive system.
