Research on Development of Simulation Interface of Engine Speed Characteristics Based on GT-POWER

Abstract

The engine speed characteristic simulation operation interface based on GT-POWER was developed by using VB6.0. VB has the characteristics of simple operation, high efficiency and powerful function. It can realize the background data modification, operation control and calculation result reading and storage of GT-Power model, and draw the engine speed characteristics after finishing the data. curve. Based on ACCESS database, the automatic input and storage of interface input data is realized. The data access, operation control and result reading of GT-POWER model are realized based on VB6.0 programming. The engine is validated by VB6.0 "PictureBox" control. Power, effective torque and effective ratio fuel consumption curve. For the needs of engine speed characteristic simulation, VB6.0 software is used for secondary development of GT-Power, and Chinese operation interface is obtained to simplify the operation process of engine speed characteristic simulation, reduce operation difficulty and improve calculation efficiency, which has certain engineering significance. The simulation method has the advantages of high flexibility, low cost, strong repeatability, and the like, and can obtain parameters that are inconvenient to measure. The results show that the developed engine speed characteristic simulation operation interface can simplify the operation process of engine speed characteristic simulation, reduce the operation difficulty and improve the calculation efficiency.
