The Finite Element Analysis and Optimization of Micro Free Piston Swing Engine’s Strain Interference

Abstract

MFPSE, Micro Free Piston Swing Engine, is a new type of miniature internal combustion engine based on the working principle of two-stroke swing engine. The successful development and operation of this type of miniature internal combustion engine provide important significance for the miniaturization of the internal combustion engine, and provide a number of important research theory, computation method and experimental data. In this article, according to the work characteristics and co-ordination requirements of MFPSE (Micro Free Piston Swing Engine), whose strain interference is analyzed using finite element analysis software, the problems and interference of the center pendulum and cylinder is found evidently. The data of analysis provides theory basis for the MFPSE’s structural optimization, and is critical to improve the performance of MFPSE.

Carbon Fiber Paper Modified with Carbon Nanotube for Proton Exchange Membrane Fuel Cell

“…Gas diffusion layer (GDL) is a very important component in PEMFC, which backs up the catalyst layer, provides passage for reactant gas and water generated from fuel cell, and transmits electrical energy. Carbon fiber paper is widely used as GDL substrate, and lots of research papers have been published [1][2][3][4][5][6][7][8].…”
