Analysis of the thermal behavior of a ball screw based on simulation and experimental investigation Zihan Li1, a, Kaiguo Fan1, b and Jianguo Yang1, c 1School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China alizihan123@sjtu.edu.cn, b fankg@sjtu.edu.cn, c jgyang@sjtu.edu.cn Keywords: Ball screw, Thermal behavior, Finite element analysis, Experimental investigation.
Fig.3 Schematic diagram of the finite element model The transient thermal characteristic of the ball screw during the warm-up phase is expressed as follows: (1) where A and V are the flank surface area and volume, respectively; hw is the forced convective heat transfer coefficient; ρ is the material density; specific heat is noted as c; and t denotes time.
According to Eqs. (3), and (4), the boundary conditions of the forced convective heat transfer coefficient hw and the total frictional heat qin can be calculated as: (8) where material density ρ is 7.85x103 kg/m3, specific heat c is 450.
