Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...
in this paper, a connecting rod was modeled and analyzed by finite element method. byusing genetic algorithm (ga) and modified cuckoo optimization algorithm (mcoa), the materialproperties and some geometrical specifications were optimized. cost function was a combination ofweight and stress. the connecting rod was under a load of 21.8 kn which obtained 360o crank angleat 5700 rev/min. the reduc...
Some reciprocating compressors have connecting rods with ball joints to join the crankshaft and the piston. The load of the pressurized gas inside the cylinder directly loads the joint of the piston and the connecting rod. For this reason, it needs to be highly reliable, so it needs to be made of hard material, high-precision spherical surfaces, and a complicated assembling line. Accordingly, t...
in order to reduce wear in gudgeon pin, bush and piston boss lubrication is done. oil used in national engine species was 10w40 with dynamic viscosity 5.5 mpa.s at 140 °c (the working temperature). in order to complete investigation the oil film hydrodynamics analysis in small end of connecting rod, a real full model engine with four cylinders has been simulated by avl excite5.1 software. in th...
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...
In series of automobile engine components a connecting rod is highly critical and researchable one. The main idea of this study is to do analysis of connecting rod and get idea of stress producing during compressive and tensile loading. And then give idea about weight reduction opportunities for a production steel connecting rod. This has entailed performing a detailed load analysis. Therefore,...
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...
Connecting rod is a crucial part of the reciprocating compressor and the crankpin bearing fault of connecting rod is always the obstacle in fault diagnosis. Normally the condition monitoring of connecting rod and dynamic analysis are based on cylinder dynamic pressure monitoring which is also an important method for fault diagnosis. However, it is hard to diagnose crankpin bearing fault in real...
Connecting rod is the intermediate link between the piston and the crank. And is responsible to transmit the push and pull from the piston pin to crank pin, thus converting the reciprocating motion of the piston to rotary motion of the crank. Generally connecting rods are manufactured using carbon steel and in recent days aluminium alloys are finding its application in connecting rod. In this w...
