Simulation Of Complex Systems In The Leaf Disc System

A typical complex system -the bladed disk system is as a engineering background in the text.Aiming at shortcomings and technical difficulties of the existing dynamics methods researching at the dynamics characteristices of complex system, the complex systemic research on the similitude theory and dynamics simulative methods is presented.The main research contents as follows:1. The basic principles for similarity of the general systems are advanced based on the perspective of "general systems theory",thus,the similitude theory and method which can be applied to research on general systems is established.The method provides a theoretical basis for studing the same phenomenon and laws of various systems in nature.2. A new method of comples systems similarity measurement is presented based on the similitude theory and method of general systems.So the method provides a theoretical basis and technical guidance for building test models in engineering practice.3. The dynamic similarity conditions for different energy systems are analysed based on the bond graph which is an effective tool for modeling of system with multi-energy domains,and a simulation method which can be widely used to study dynamics characteristices of complex systems are advanced.4. The similarity analysis and research of complex bladed disk system is carried out by utilizing the methods of dynamics simulation and similarity measurement,and model test is studied.Aiming at complex system with characteristics such as multi-energy domains coupling,systematization and so on, a simulation method which can be widely used to study dynamics characteristices of complex systems are advanced based on researching on the basic principles for similarity and similarity measurement. This method is to map the original system model to another more easily simulated model, through simulating the characteristices of the mapping model to achive the purpose of studying dynamics characteristices of the original system model. The dynamics characteristices can be derived efficiently,conveniently and intuitional when the method is utilized to dynamics simulative test of complex mechanical systems,so new ideal and methods have been provided for dynamics research of complex mechanical systems.
