Problems solved by technology

However, the current detection device can only detect the relationship between the performance of the static pressure air bearing and the shape of the bearing, throttling mode, geometric parameters and air supply pressure, but the direct factor that affects the performance of the bearing: the pressure distribution of the gas in the bearing cannot Direct detection cannot directly analyze the pressure change of the gas in the bearing caused
