“…Calculation parameters are also shown in Table 1, and the depth value of the pressure equalizing groove does not change with the pressure. At this time, we can obtain the film pressure distribution of the aerostatic bearing with REPG by solving (12), as shown in Figure 7. Suppose that this calculation is a computational model 2.…”

“…Belforte et al [9] studied the influence of the bearing groove on the bearing pressure distribution, gas consumption, and stiffness. This work was also done in some studies [10][11][12]. Another way is through the electric or pneumatic precision electronic components to control the throttle effect of aerostatic bearings, in order to obtain high stiffness [13].…”

“…where C d,or is the discharge coefficient of the orifice, A or = πR 2 1 is the area of the orifice, R s is the specific gas constant of air, T is the air temperature and κ is the adiabatic expansion coefficient [13]. Furthermore, it must be equal to the mass flow from underneath the orifice to the inlet of the air bearing gaṗ…”

“…Basınç dağılımının hesaplanması için kullanılan çözüm tekniklerinin iyileştirilmesi ve daha hızlı sonuçlar veren algoritmaların kullanılması son zamanlarda BHY konusundaki çalışmalarda sıklıkla yer almaktadır. Bunun yanı sıra [14]'de verilen momentum denklemi gibi doğrusal olmayan akış problemleri için sıklıkla kullanılan paket programları da (Fluent, Ansysis-CFX) Reynold's denklemi çözümlerinde tercih edilebilmektedir [15]. Czolczynski, [16] Reynold's denkleminin çözümünde değişen yönlü kapalı nümerik integrasyon metodunu kullanarak, 38 µm boşluk miktarına sahip basınçlı hava yatağı için basınç dağılımını hesaplamış ve çözümü hızlandırmıştır.…”
