Abstract    High-speed maglev train is considered an ideal vehicle in the 21st Century, as an important part of the train, the travel mechanism bears and delivers a variety of vertical and horizontal alternating load in operation, it affects the operation safety of the train directly, so key components of the travel mechanism should under fatigue strength test by fatigue test machine.The paper proposed a variable frequency pump control fatigue test machine for high-speed maglev train, simplified the structure and improved the stability and reliability by using variable frequency pump control technology to regulate the velocity of the motion of hydraulic cylinder. Introduced the operating principle of the system, established the simulation model include frequency converter, electromotor, hydraulic system. The system performance in the cases of variable load and variable speed is analyzed with the SIMULINK of MATLAB. The system is verified correct and feasible by comparing simulation results with the actual situations, finally optimized control performance of the model system by using PID closed-loop controller as well. The variable frequency pump control fatigue test machine achieved high response and high energy efficiency, so it is suitable for fatigue test application.

چکیده    قطار ماگلو با سرعت بالا به عنوان یک وسیله نقلیه ایده آل در قرن 21 در نظر گرفته شده است. مکانیسم سفر به عنوان بخش مهمی از قطار، بار متناوب عمودی و افقی وسیعی را در عمل تحمل کرده و حمل می کند. آن بر ایمنی عملکردی قطار به طور مستقیم تاثیر گذاشته، در نتیجه اجزای کلیدی مکانیسم سفر باید تحت آزمون استحکام خستگی توسط دستگاه تست خستگی درآید. در این مقاله، یک دستگاه تست خستگی پمپ کنترل با فرکانس متغیر برای قطار ماگلو سرعت بالا ارائه شده است. آن ساختار را ساده کرده و ثبات و قابلیت اطمینان را با استفاده از فناوری کنترل پمپ با فرکانس متغیر به منظور تنظیم سرعت حرکت سیلندر هیدرولیک بهبود می دهد. با معرفی اصول عملکرد سیستم، مدل شبیه سازی از جمله تبدیل فرکانس، الکتروموتور و سیستم هیدرولیک ایجاد شده است. عملکرد سیستم در موارد بار متغیر و سرعت متغیر با SIMULINK از MATLAB مورد آنالیز قرار گرفت. سیستم از نظر درستی و عملی بودن با استفاده از مقایسه نتایج شبیه سازی با موقعیت های واقعی تایید شده است.در نهایت، عملکرد کنترل سیستم مدل با استفاده از کنترل کننده حلقه بسته PID بهینه سازی شد. دستگاه تست خستگی پمپ کنترل با فرکانس متغیر پاسخ بالا و بهره وری انرژی بالا را به دست آورد، در نتیجه برای کاربرد تست خستگی مناسب است.
