A NOVEL CONCENTRIC ANNULAR CLEARANCE MEASURING METHOD BASED ON PNEUMTAIC FLOWREATE BALANCE

Abstract

A novel method of measuring the annular concentric clearance is proposed to estimate the clearance height between the piston and the cylinder. The principle of the method is that pneumatic flow rate through the clearance is an assured function of the height and the upper stream pressure of clearance. Firstly, the measuring principle was proposed. Then the simulation model was built in AMESim, and the clearance-pressure data tables were obtained. Finally, the experiment was carried out, and the results showed that the clearance measuring method was effective and can be used to estimate similar clearances.
