Method of Vector Closed Contours in Design Problems of Study Course 'Internal Combustion Engines: Kinematics and Dynamics'

摘要

The paper discusses the method of vector closed contours as a mean of simulation and analysis of kinematics and dynamics of internal combustion engine (ICE). Being realized in the KDAM software it provides students with powerful tool for making deep analysis of key ICE parameters. Among the topics of Machine and Mechanism science (MMS) that can be considered with KDAM and solved by students while performing the design project are: single-loop and two-loop vector models of a mechanism: analysis of how changes in kinematic parameters effect the chosen optimization goal; creating complex kinematic schemes of ICE main mechanism with different relationships between parameters; creating dynamic vector model; plotting indicator diagram for the ICE working stroke: performing analysis of the mechanism dynamics: finding reactions at hinges and supports; parametric synthesis using kinematic and dynamic criteria, and some others. Working up the above topics, students should learn how to solve basic design problems for ICE main mechanism, as well as for other similar mechanisms within study of MMS course.
