A fast numerical method based on static reduction for the solution of the contact problem of the piston ring

矿业科学学报, 2017
This paper provides a fast method based on static reduction for the solution of the displacements of the piston ring's contact nodes. The nodal displacements and the corresponding nodal forces of the contact nodes are connected by the contact stiffness ...

Numerical analysis of a free piston problem

Mathematical Communications, 2010
The problem considered is the Stokes and Navier-Stokes flow through a system of two pipes in the gravity field; inside a vertical pipe there is a free heavy piston. Theoretical analysis, the existence and non-uniqueness of solution, has been completed recently by the authors.

A model of piston impact and vibration for internal combustion engine noise reduction

Archives of Acoustics, 2016
In this paper a mathematical model is developed to study piston impact and cylinder liner vibration in internal combustion engines. The aim of this study is to assess the effect on cylinder liner response (and, therefore on piston-impact induced noise ...

Magnetically Coupled Free Piston Stirling Generator for Low Temperature Thermal Energy Extraction Using Ocean as Heat Sink

Journal of Marine Science and Engineering
The ocean, as one of the largest thermal energy storage bodies on earth, has great potential as a thermal-electric energy reserve. Application of the relatively fixed-temperature ocean as the heat sink, and using concentrated solar energy as the heat ...

Simulation study on the operating characteristics of FPEG based on variable load control

Advances in Mechanical Engineering
To stabilize the operation of free-piston engine generators (FPEGs), a variable load control strategy is proposed to regulate piston motion. By dynamically adjusting the equivalent load to control the system’s total resistance, the strategy alters the ...
