Abstract This paper presents a mathematical model of piston-rings-cylinder sealing (TPC) of a combustion engine. The developed model is an itegrated model of gas flow through gaps in TPC unit, displacements and twisting motions of piston rings in ring grooves as well as generation of oil film between ring face surfaces and cylinder liner. Thermal deformations and wear of TPC unit elements as well as heat exchange between flowing gas and surrounding walls, were taken into account in the model. The paper contains descriptions of: assumptions used for developing the model, the model itself, its numerical solution as well as its computer application for carrying out simulation tests.

Data Basis

Computer application technology which is changing with each passing day has shown strong vitality, and garment CAD technology has become the inevitable trend in garment industry and it is accelerating economic development. The relation between control parts and details for female jacket structure was established by applying stepwise regression and using C++ language. By comparing between different mathematical models, it was discovered the waist and hip had more influence to the small bust female jacket structural design. The conclusion will provide the garment pattern making experience for clothing enterprises, and it will provide data basis for garment CAD technology.
