Strength Analysis of the Connecting Rod of 12V180 Internal-combustion Engine

The connecting rod plays a very important role in operation of the internal-combustion engine,whose strength and reliability must be very high because of its special work environment.The paper carrys out the strength analysis to 12 V180 internal-combustion engine connecting rods using the software of ANSYS,ascertains its intensity distribution,finds the dangerous area and calculates its safety factor of the fatigue damage under the dynamic load.The results provide the theory basis for making improvement and design of the connecting rod.
