Process capability improvement of an engine connecting rod machining process
Statistical process control is an excellent quality assurance tool to improve the quality of manufacture and ultimately scores on end-customer satisfaction. SPC uses process monitoring charts to record the key quality characteristics (KQCs) of the component in manufacture. This paper elaborates on one such KQC of the manufacturing of a connecting rod of an internal combustion engine. Here th...
متن کاملStress and Fatigue of Connecting Rod in Light Vehicle Engine
The connecting rod (CR) is the main moving parts and an important component of engine. If the reliability is not strong enough, fatigue failure of the CR would occur, thereby leading to component fracture and engine failure. So much so that CR fracture. It will lead to engine fault as well as serious outcome. In this paper, stress distribution and fatigue life of CR in light vehicle engine were...
متن کاملLarge-eddy simulation, fuel rod vibration and grid-to-rod fretting in pressurized water reactors
The grid-to-rod fretting (GTRF) problem in pressurized water reactors is a flow-induced vibration phenomenon that results in wear and failure of the cladding material on fuel rods. Grid-to-rod fretting is responsible for over 70% of the fuel leaks in pressurized water reactors in the U.S. The GTRFinduced wear process involves turbulent flow, mechanical vibration, tribology, and time-varying irr...
متن کاملFinite Element Analysis of Connecting Rod
Abstract—The connecting rod transmits the piston load to the crank causing the latter to turn, thus converting the reciprocating motion of the piston into a rotary motion of the crankshaft. Connecting rods are subjected to forces generated by mass and fuel combustion. This study investigates and compares the fatigue behavior of forged steel, powder forged and ASTM a 514 steel cold quenched conn...
متن کاملConnecting Rod Evaluation
Since 1986, more than 500 million powder forged (PF) connecting rods have been manufactured and installed in automobiles worldwide. The application of forging a preformed near-net shape consolidated from metal powder has been widely accepted since the early eighties and today is the preferred manufacturing technique for 60% of the connecting rods manufactured in North America. The remaining por...
