“…Thin film pressure sensors are used to measure high pressure on the order of 1 GPa but the pressure is generated in engines on the order of 10-100 MPa, a sensor with reduced and uniform strain sensitivity has been developed by optimizing the composition of copper, manganese and nickel contained in the sensor alloy [11]. However, in hydrodynamic linear guides, it is not possible to use thin film pressure sensors because of very small pressure difference of 0.5 MPa [13].…”

Test-stand with Plexiglas rail and different integration methods of pressure sensors used by Ibrar [13] The machine table has run for forward strokes for different feed-rates and pressure is measured through three sensors integrated in a Plexiglas rail. A surface pressure of machine table of 0.24 bar is considered to study the pressure inside the lubrication gap.…”

“…and PG-PS-3. Machine table with Surface pressure of 0.24 bar is considered in this case [13] For the generation of oil film pressure, it is also important to improve a lubrication cycle. From the pressure curves measured using sensors integrated in Plexiglas rail, it has been observed that due to poor lubrication and relative movement, air is entrapped inside the lubrication gap.…”

“…6. The pressure sensors were again calibrated hydrostatically according to the method described by Ibrar [13], after they were integrated (with favourable integration method) into the steel-rail. After the integration of pressure sensors inside steel rail, it was crucial to perform hydrostatic and hydrodynamic calibration of sensors integrated in the steel rail.…”

Previously, a 2D simulation model for hydrodynamic linear guides with two reduction factors has been developed to calculate oil film pressure and floating heights/angle numerically. However, no method was available to verify the oil film pressure experimentally but only with floating heights measurement. Therefore, different pressure sensor's integration methods were tested in a stationary Plexiglas rail to measure fluid film pressure inside the lubrication gap. The pressure sensors were statically and dynamically calibrated. However, floating heights could not be measured with the preliminary used Plexiglas rail. This paper reports the suitable integration of pressure sensors into a stationary steel rail to compensate this drawback. It focuses on the measurement of pressure rise using pressure sensors inside the lubrication gap in combination with the floating heights. Experimental results have shown that the oil film pressure inside the lubrication gap can be measured using pressure sensors, which draw conclusions about cavitation and lack of lubrication. The variation of oil film pressure measured along the length of the carriage can be used to improve the simulation model i.e. the reduction factors. The pressure measurement can help to identify the lubrication conditions and further actions can be taken to improve the lubrication cycle.
