油膜轴承的结构参数对其承载能力和油膜刚性起决定性的作用，轴承结构参数主要包括腔型结构、油腔数目、节流器参数等。对上述参数进行了分析，对腔式及垫式静压轴承、偏心油楔及阶梯腔的动静压轴承进行了静态设计计算，运用数值计算方法结合MATLAB软件编程求解了轴承结构参数与油膜承载能力间的相互关系。结果表明：阶梯腔结构相比于其他几种结构形式的动静压轴承具有更为理想的承载能力。

Structural parameters, such as the structure of recesses, the number of recesses, and throttle parameters, play decisive roles in determining the carrying capacity and rigidity of oil film bearings. These parameters are analyzed, and a state design is presented for a hydrostatic cavity and pat bearing, a hybrid bearing with an eccentric oil wedge, and ladder recesses. The mutual relationships between oil film bearing structural parameters and carrying capacity are calculated by combining numerical methods using MATLAB software programming. The results show that hybrid bearings with ladder recesses have superior carrying capacity compared to bearings with other structural forms.
