Qualitative bond-graph based fault diagnosis for liquid-propellant rocket engine;

The transverse vibration model based on the power bond graph is established in margin-single-gear transmission ball mill system,the equation is set up.

Taking YFD hydraulic profiling tool carrier for example,computer dynamics simulation on transition process of hydraulic servo system has been completed with power bond graph and space-state method in this paper.

In this paper,the dynamical model of the reciprocating pulsating-flow hydraulic system is developed by means of power bond graph.

The development and present status about dynamic theory and analysis software of systems based on bond graphs;

Dynamic studying on planetary gear transmission system based on bond graph;

Application of power bond graph on dynamic characteristics of a new counter balance valve;

Bond graphs was used to model the high speed on/off value,and a handy method for rebuilding the system modeling was put forward through combining the advantages of both bond graphs and high speed on/off value.

Bond graphs and SIMULINK were used to modal and simulate the constant pressure valve,and a new method for dynamic design and analysis of constant pressure valve was put forward through analysis the dynamical characteristic of the valve core.

The basic components for design synthesis are defined with their input/output characteristics and energy functions by the bond graphs.
