“…As a new type of non-contact bearing, a gas-extruded membrane bearing relies on the squeeze effect of a gas film to control the gas flow and pressure distribution for the smooth operation of the bearing [1]. It demonstrates advantages such as low friction, high precision, the capacity for self-lubrication, and environmentally friendly status, which make it widely applicable to high-speed rotation and precision motion applications in settings such as wind turbine power generation [2], aerospace engineering [3], precision machine tooling [4,5], automotive fuel cells [6], micro-gas compressors [7][8][9][10], and more.…”

In this study, a novel gas-extruded membrane bearing was developed, and an optimization algorithm was applied to solve a Reynolds equation that describes the load-bearing characteristics of this bearing. This was effective in improving the solution rate of the Reynolds equation, significantly reducing the difficulty of obtaining a solution, avoiding high programming difficulty, and achieving a high solution accuracy. Through a comparative analysis, the error in the accuracy of the alternating implicit difference method was addressed, and the traditional finite element method for solving the same model was verified, with an average error of 2% reached to verify its applicability. The algorithm was also used to analyze the load-bearing capacity of the gas-extruded membrane bearing. This revealed not only a positive correlation of the average load-bearing capacity of the gas-extruded membrane bearing with the frequency and amplitude of vibration but also a negative correlation with radial clearance, with the cut-off frequency reaching 19 Khz. The load-bearing capacity of the gas-extruded membrane bearing proposed in this paper reached 1.28 N, which indicated an error of 3.28% with the theoretical approach. To sum up, this research provides an important reference for the design and manufacture of novel gas-extruded membrane bearings.
