Abstract: Gas-bearing technology is widely applied in linear compressors to enhance reliability and extend service life. Fluent was employed to calculate the 3D model of a linear compressor gas bearing and analyze the effects of dynamic characteristic parameters. The results demonstrated inflatable pressure and pressure ratio positively influence gas-bearing load and flow, with gas-bearing load being highly sensitive to different operating points of inflatable pressure. Based on these calculations, the dynamic characteristic parameters of the linear compressors were further optimized to satisfy the gas-bearing index. Simultaneously, the negative impact of bearing load was reduced, thereby improving the efficiency of the Stirling cryocooler.
