Single-cylinder Internal Combustion Engine Crank Linkage Dynamics Computer Simulation Study

In order to fhrther study the kinetic disciplinarian of the crank ?connecting rod mechanism of ICE (Internal Combustion Engine), vibration of cylinder block which is caused by inertia force of the mechanism and the balance problem of inertia force, taking SI 95 diesel as an example. the text studied dynamics computer simulation of single-cylinder ICE?crank-connecting rod mechanism0 Using Pro/Engineer, the CAD software, 3D solid model of the mechanism was built and parts of the mechanism was assembled to piston components connecting rod component and crank component. then, connected with Multibodies simulation software (Working model 3D) and built dynamics model Without thinking air-pressure force~ friction resistance~ loads acting on the crank, the text mainly studies inertia forces of the mechanism (reciprocating force.. centrifugal force) which function on the cylinder block and the balance problem 0 The results show that there is cc~mputational error between the theoretical computation which has been simplified according to the static equivalent principle and the real computation; modifying mass parameters (center of mass.. mass ) of crank have different effects on the cylinder block, especially the arrangement of counterw~gbting The studies can provide grounds for the optimize design and the selection of mechanism.
