This article analyzes the sharing and reuse of the geography model in the distributed environment based on the methods of geography model integration and framework. We use the model contract to describe the integration of geography model, and design a model contract language to express. We also design the model execution engine architecture which can execute the model contract language. This is the...
In order to increase the power density of the piston engine, the power transmission mechanism of a twin-rotor piston engine based on differential velocity principle is introduced. Firstly, the precept of the engine principle is developed, and the velocity of the rotors is designed, then the structure and the kinematic simulation of the power transmission mechanism are derived. The results show that...
In order to increase the power density of the piston engine, the power transmission mechanism of a twin-rotor piston engine based on cycloid is introduced. The twin-rotor piston engine has a number of advantages compare to other piston engine type. The combination method of its unique power transmission mechanism which use the cycloid and the crank-rocker mechanism creating a cyclic rotary motion...
