Research on Designing and Manufacturing the Connecting-Rod Big End Bearing Equipment

The paper researches on designing and manufacturing system that can measure the force acting on the connecting-rod big end, thereby investigating the temperature and pressure of oil film in the it. The experimental equipment simulates the loading diagram of the internal combustion engine in 4 sessions. The connecting rod by optical elastomer material is studied by the method of using the model of connecting rod. The testing equipment can operate in a range from 0 rpm to 250 rpm. When the speed of the bearing changes, the load pattern acting on the connecting-rod big end will change, the temperature and pressure of oil film will change, too. The researching equipment in the field of lubrication and internal combustion engines can be used to verify theoretical research results and numerical simulations
