Design And Modeling On Motorcycle Engine Dynamometer Power Control System

With the widespread application of motorcycle, the requirement for discharge and other performance of motorcycle is becoming stricter and stricter. The motorcycle engine performance testing is an important step in manufacture, maintenance and research. The motorcycle engine testing table is a main equipment for engine performance testing, and a foundation of other testing equipments. This article focuses on simulation and research based on asynchronous exchange of motorcycle engine dynamometer power control systemFirstly, this article introduces the basic principles of the system, the operating principle and the relations among the main torques of the system and discusses the stability conditions of the system. All of the above lay a solid theoretical foundation for the system's set up. Secondly, this article elaborates the system from the following aspectsFrom the aspect of hardware designing, this article introduces the design of the system, elaborates the operating principle of the dual-CPU system, suggests a design method to the man-machine interface, and explains the working principle of dual-port RAM. After that, this article makes a detailed description of the design of the accelerator control system and analyzes the debugging process.From the aspect of software designing, this article focuses on the host computer program design based on the Labview, lists the main program flow chart, and makes a detail classification description introduction to modularization of software design. Collects data through the serial ports communication, processes data through the median filtering, and storages and charts data through statements.From the aspect of simulation, this article sets up mathematical model for dynamometer system on the basis of analysis of various models. The simulation was set up through Simulink. This article uses a certain kind of method to make a simulation of the system, and then the simulation curve is obtained. At last, comparing the simulation results to experimental results, verifies the correctness of the mathematical model. It has a guide sense to the system controlling.This article makes a comprehensive elaboration to the dynamometer system. The experimental results verifies the simulation model's correctness and the design of the system can achieve the requirement of the engine testing.
