Friction-loss and vibration analog experimental equipment for main motion components of IC engine

Abstract

A tester used for simulating wear-out and vibration of main movable parts on internal combustion engine consists of master driving system formed by air cylinder, piston ring, piston, crankshaft, inlet and outlet of high pressure air; state monitoring system formed by pressure transducer and vibration transducer on bearing base, oil monitoring transducer and temperature transducer as well as vibration transducer on machine rack, and dynamic transducer on crankshaft. It is featured as utilizing high pressure air to simulate explosion pressure in air cylinder and to simulate operation condition causing wear-out and vibration of cylinder sleeve and piston ring pair in said engine.

Description

technical field

[0001] The invention relates to testing equipment, in particular to a friction, wear and vibration simulation testing machine for main moving parts of an internal combustion engine. Background technique

[0002] Cylinder liners, piston rings, crankshafts, bearings, etc., as the core components of internal combustion engines, work under high temperature and high pressure for a long time, and the working conditions are harsh. For a long time, the research on the friction and wear of these moving parts has made some progress, but due to the influence of its working environment and technical means, there are still many defects. Searching the existing patent technology literature found that the following are related to this patent: the invention patent "piston ring-cylinder liner material friction and wear performance test device" (application number: 200410068042.5) mainly provides cylinder liner-piston ring in The wear performance in different environments, the...
