Kramskoy A. The perfection of the methods of calculation dynamic of pneumatic valve and pneumatic brake drive of the vehicle

Object of research: process of the current of the compressed air in cavity of pneumatic valve and in pneumatic brake drive of the vehicle. Research purpose: perfection of the methods calculation dynamic of pneumatic valve and pneumatic brake drive of the car on base physical and mathematical modeling of the transient processes. Research methods: in process of the determination of the condition of the question and stating the problems of the studies were used methods of the collection, choice and analysis information. For researches the compressed air dynamic in cavity of pneumatic valve were used methods mathematical and computer modeling, methods to solve ordinary differential equations and differential equations in partial derived (method of control volume); when processing result experimental researches - a method correlation analysis. Equipment: Pentium - 2,6 MHz, 512 Mb RAM, Windows 2000, Office 2000, Matlab 6.5, Simulink 5.0, gcc 3.4.2. Theoretical and practical results: designed modified the method of calculation for modeling of the transient processes in cavity pneumatic valve brake drive of the vehicle. Implementation: the Poltava Plant OSS "PAAZ" and Volchansk plant OSS "VAZ" is applied the results in industry of perspective pneumatic valve and pneumatic brake system. Economy branches it is used in: a transport machine-building.
