Investigation of Torsional Vibration Characteristics of Marine Diesel Engine Crankshaft System
Evaluation of the torsional vibration characteristics of a crankshaft system is indispensable to the development of marine diesel engines. It influences the selection or decision about shafting components such as the flywheel, torsional damper, generator and even modification of the crankshaft itself. In this paper, experimental and analytical investigations of torsional vibration were carried ...
متن کاملDevelopment of balance shaft and flywheel for single cylinder diesel engine based on analytical approach and comparison with the simulation result
Vibration is a key factor of abrasion and destruction in the internal combustion engine. In internal combustion engines, the main causes of vibration is combustion pressure, connecting rod weight, piston weight and inertial forces. This vibration create corrosion and fracture in main part of engine such as crankshaft, camshaft and cylinder block in long time. This corrosion and fracture is effe...
متن کاملCylinder Pressures and Vibration in Internal Combustion Engine Condition Monitoring
Abstract: We focus on the detection of incipient faults in an internal combustion engine using a minimum number of sensory information. Inducing several faults in a 4 stroke diesel engine, cylinder pressure (P) and vibration (V) data are acquired. Two sets of artificial neural nets (ANN) are trained separately, using features from the pressure and vibration data. Both sets of nets show very goo...
متن کاملFailure Analysis of a Four Cylinder Diesel Engine Crankshaft Made From Nodular Cast Iron
The premature breakage in some four cylinder diesel engine crankshafts was reported. All crankshafts were failed from the same region. Failures had occurred in the first crankpin, the nearest crankpin to the flywheel. Dynamic analysis and finite element modelling were carried out to determine the state of stress in the crankshaft. FEM results revealed that the first crankpin fillet is the most ...
متن کاملFatigue Analysis and Optimization of Crankshaft of V8 Diesel Engine
The crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. Its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. More challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...
