Abstract

Abstract: Using dynamic mesh technology, In-cylinder working process of the engine is detailedly designed in this article regarding the new swashplate revolving cylinder piston engine. We establish the numeral simulation model of the engine working process based on fluid-structure interaction, the pressure and temperature distribution of the In-cylinder gas in the six thermal process is obtained, and the temperature distribution of the hot end components is presented. The results show that the working process of the engine is reasonably organized. The biggest thermal load appears in the intake flow process. The wall temperature of the gas side is lower than the maximum allowable working temperature of the material. The temperatures of piston and cylinder sleeve of the O ring groove wall are below the maximum allowable working temperature of O ring material, which can ensure high temperature gas and cooling water reliable seals. The thermal stress of the cylinder, cylinder sleeve and piston can satisfy the strength limit.

Key words: swashplate revolving cylinder engine, dynamic mesh, working process, fluid-structure interaction
