Abstract: Interference fit is an important contact mode used for torque transmission existing widely in engineering design. To prevent trackslip, a certain magnitude of interference has to be ensured; meanwhile, the interference needs to be controlled to avoid failure of the mechanical components caused by high assembly stress. The finite element method (FEM) can be used to analyze the stress, ...

This paper takes dynamics analysis on the piston and the dynamic lubrication theory on the skirt and the ring of piston as the basis. Using AVL Glide software, through the establishment of the analysis model of the piston secondary movements, this study focuses on the effects of the crankshaft bias on piston secondary movements’ characteristics. This paper takes 5 different offsets, by comparin...

The flexibility of a crankshaft exhibits significant nonlinearities in the analysis diesel engines performance, particularly at rotational speeds around 2000 rpm. Given explainable mathematical trends analytical model and lack available modeling intake manifold with flexible crankshaft, present study develops validates such model. In paper, mass flow rate air that goes from into all cylinders e...

A frequency-modulated instantaneous crankshaft speed signal is proposed as input information for monitoring the identity of cylinder power an internal combustion engine. Algorithmic software based on solving a predefined system linear algebraic equations with optimization solution least-squares method. Frequency and time methods measurement research are investigated. In temporal representation,...

The research was carried out in order to develop a method for skipping fuel supplies (turning off individual piston strokes) at low frequencies of crankshaft rotations and partial engine operating modes with direct-acting supply systems increase efficiency. developed is easily implement using ring-type discharge valve electronic control. A made the form split elastic ring installed high-pressur...
