【Abstract】 In order to study the radial pressure distribution pattern of piston rings, this paper analyzed the weakness of traditional measuring method of piston rings pressure and studied the relation between deformation and pressure of piston rings, an useful electrical measuring method of piston rings pressure was presented. The results showed that the method was reliable, with good repeatability and high accuracy.更多还原
