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...

In this paper, we introduce the production of ductile iron crankshaft of the engine status quo and development. Ductile iron crankshaft discussed smelting process, alloying and manufacturing process mode. This paper focuses on the application of isothermal hardened spheroidal graphite cast iron in the crankshaft, especially its application in the power of the engine crankshaft. We also introduc...

The main objective of writing review on fatigue life of crankshaft is to investigate the behavior of crankshaft under complex loading conditions. Automobile industries are always interested to develop a new product which will be innovative and fulfill market expectations. All the engine components are subjected to constant to varying load which also varies in direction and due to these, compone...

In order to simulate the Stirling engine more easily, the stiffness and damping ratio of the crankshaft bearing are assumed to be steady-state in the research before, but this assumption is contrary to the real condition. Therefore, in this paper, a time-varying stiffness and damping ratio of the crankshaft bearing simulation method has been proposed. Compared with the simulation results of the...

Based on the V-type diesel engine crankshaft system, the paper combined the finite element method (fem) and multi-body dynamics method together, made a virtual simulation analysis. First, by 3d software and finite element software to establish the multi-body dynamic models of the crankshaft, bearing and piston, then simulated the actual engine working condition, and got the data such as cranksh...

The reliability of any mechanical system, in which the linear displacement of a piston is converted into the rotation of a power transmission shaft, strongly depends on the reliability of the crankshaft. The crankshaft is the critical component and any damage occurring to the crankshaft may put the mechanical system out of order. The numerical finite element simulation of crankshafts with multi...

This study investigates dynamic & static behaviour of automotive engine crankshaft with the specific conditions. This work investigates the coupled modes, including, couple torsional flexural vibration and coupled longitudinal flexural vibration for non rotating engine crankshaft. The finite element models of this generally used are in two categories beam elements and solid elements and in this...

This paper introduces Crankshaft, a MAC protocol specifically targeted at dense wireless sensor networks. Crankshaft employs node synchronisation and offset wake-up schedules to combat the main cause of inefficiency in dense networks: overhearing by neighbouring nodes. Further energy savings are gained by using efficient channel polling and contention resolution techniques. Simulations show tha...

The deflection of the crankshaft which transfers the power of motor to the pump of the compressor directly affects the vibration, noise and wear problems in the rotary compressor, therefore, with the requirement of higher reliability, it is important to obtain it exactly in compressor design. Various forces that the crankshaft suffers are calculated by theoretical analysis in the operation proc...
