Abstract


Hydraulic free piston engine is started from the 1980s caused widespread worldwide attention, collection of modern hydraulic technology, microelectronic technology, control technology and engine technology in a medium-sized power in frequent starts and stops walking with good mechanical promising specialty engines. The structure of the traditional engine crankshaft the engine is significantly different, that its control system is made a lot of special requirements. This thesis focuses on hydraulic free piston engine experimental prototype dual characteristics and control requirements to IPC machine core, using IPC IPC board structure, made of two kinds of electronic ignition control scheme, the completion of the engine control system experimental prototype hardware and software design. On this basis, the completion of the prototype debugging tasks and conduct the ignition experiments. Paper is divided into seven chapters: Chapter 1: Introduction of hydraulic free piston engine's basic situation, described the composition of the engine control system and its key technologies overview of the development and discussed the free-piston engine prototype hydraulic double its control system requirements Research and its control system, and finally introduces the significance of the topic of this thesis and research content. Chapter II: Analysis of hydraulic free piston engine experimental prototype dual control system unit case, it made a preliminary selection, and finally control system includes both hardware and software has made an overall design. Chapter III: Introduction of hydraulic free piston engine experimental prototype dual control system core - industrial computer control system hardware structure and elaborated signal detection and processing circuit design content, followed by a focus on the control system two kinds of ignition system - positional and displacement-type ignition system, and finally the hardware system reliability and robustness made some research. Chapter 4: Prototype of the hydraulic engine control system software solutions analyzed were elaborated using Turbo C and LabWindows / CVI programming tool case, and software system reliability and robustness to do some research. Chapter Five: describes the maximum voltage secondary ignition coil and spark plugs gap breakdown voltage calculation method, the dynamic process of the ignition system established mathematical model and its simulation using Matlab, and finally measuring the ignition voltage curve, verify the simulation results. Chapter VI: elaborated double free-piston engine prototype test bench with the purpose of this experimental study, prototype engines were introduced and preliminary experiments formal commissioning phase during the experiment, and their results, and the results analyzed. Chapter VII: The paper summarizes the work, and further work is put forward their own ideas.
