“…The integration transformation equations were applied by Floquet et al [20] in the analysis of three-dimensional heat problems for bearings. The following studies took the friction heat flux as the boundary conditions to predict the temperature field, considering imperfect contact surface [21][22] and different thermal parameters [23]. The finite element analyses [24][25][26][27] were also employed to calculate the contact temperatures, which agreed well with the experimental results.…”

Dry friction dampers in turbomachinery not only decrease the vibration level, but also generates frictional heat. This thermal process may cause a significant temperature rise at the contact interface, producing thermal expansion and altering tribological properties subsequently. These effects in turn can change structural dynamics. Besides, the temperature rise may also cause the material melting and ablation, leading to damper failure. Hence, the structural dynamics and the thermal process in dry friction systems are interacting. The thermomechanical coupling should be included in analyses. In this paper, a novel numerical method, namely Dry Friction ThermoMechanical Coupling Response Prediction (DFTMCP), is proposed. Based on the multi-harmonic balance method, the DFTMCP can synchronously predict the nonlinear forced response and interface temperature in the steady state. This method is under the framework of steady heat transfer assumption, and a dimensionless number is proposed to determine the rationality of the assumption. To guarantee efficiency and convergence, an ad-hoc model reduction technique for the nonlinear thermomechanical coupling problem and the corresponding analytical Jacobian matrix, which are also the highlights of the work, are implemented. The former reduces the dimension of the governing equations by over 98.6% while the latter makes the time cost drop over 37 times. By using the proposed numerical scheme, two essential coupling factors, the thermoelastic deformation and the friction coefficient variation at the interface, are considered and discussed quantitatively for the influence on the forced response through the finite element model of a blade with a flat under-platform damper in engineering. Results show that under the specific rotational speed, the average temperature at the contact surface rises by 364.16°C, and the maximum local temperature increases to 1198°C, which is close to the melting point. Ignoring the thermomechanical coupling effect leads to a 25% misprediction of the optimal centrifugal force and a 27.4% underestimation of the resonant peak.

“…Surface heating at a sliding contact interface has long been of interest. Most studies [1][2][3][4][5][6][7][8] involving this aspect have focused on unidirectional sliding. In contrast, the heat source is time-varying, and the sliding motion is periodic in sliding contact involving reciprocating motion, which is anticipated to behave differently not only in terms of its different tribological characteristics but also in its thermal response.…”

In order to study the heat transfer characteristics between two rough surfaces of two contacting blocks with different bulk temperatures and sliding reciprocating motion, a two-dimensional heat transfer model was used to analyze the dimensionless average heat flux, considering thermal contact conductance. The results of a series simulations were presented, covering a wide range of operating parameters including dimensionless amplitude [Formula: see text], dimensionless frequency [Formula: see text], and measurements of interface conductance [Formula: see text]. The results show that the dimensionless average heat flux increases with the increase of dimensionless frequency and amplitude, and the dimensionless average heat flux rises sharply in the low range of [Formula: see text] and approaches to a steady state approximation when [Formula: see text] and [Formula: see text].
