“…This session proposes to safeguard manufacturing innovation and development and accurately assess manufacturing EC. For example, scholars [12][13][14][15] studied the EC characteristics and damping characteristics of the connection structure of mechanical equipment based on the Iwan model, which provides a reference for energy saving and reducing the EC of mechanical equipment to ensure the overall performance of MT.…”

CNC machine tools play an important role in manufacturing and are characterized by high total energy consumption and low energy efficiency. The energy consumption characteristics of the machine tool itself determine the total energy consumption and pollutant emission during its service life. Therefore, it is particularly important to design machine tools with energy consumption as the optimization target to analyze the composition of energy consumption and related characteristics, build a corresponding model based on reliability verification, guide the structural design and optimization according to the model, and ultimately use the evaluation system to evaluate and judge the overall energy consumption. In this paper, from four perspectives—the composition of the energy consumption of machine tools, modeling methods, design and optimization methods, and evaluation methods—with energy consumption optimization as the entry point, we analyze the research on CNC machine tools based on energy consumption around the world. The research results indicate that we should look forward to the role of energy consumption in the design of machine tools.

“…Additionally, the finite element method has been employed to investigate the stickslip contact friction behavior of bolted joint interfaces. Various contact constitution approaches have been utilized to simulate the friction contact behavior of the bolted joints, i.e., bonded constraint [29], the standard penalty method [30][31][32] and the Lagrange multiplier method [33]. However, these approaches mentioned above overlook the influence of micro-scale memory effect.…”

A novel penalty contact constitution was developed to replicate the hysteresis memory effect observed in contact interfaces. On this basis, a refined finite element analysis (FEA) was performed to study the stick–slip friction contact behavior of bolted joint interfaces. The analysis was validated by comparing it with the experimental hysteresis loops in the literature. The simulated hysteresis loops were subsequently used to identify four parameters of the Iwan model. Additionally, the effects of bolt clamping, friction coefficient, and excitation amplitude were individually examined. It was found that the deterioration in bolt clamping performance resulted in a decrease in both the equivalent joint stiffness and energy dissipation. Similarly, the reduction in the friction coefficient yielded a comparable impact. Furthermore, the identified model parameters of critical stick–slip force and displacement exhibited a quasi-linear relationship to the bolt preload and friction coefficient.
