This paper simulates how the additional flutter signal impacts on oil pressure and actuator output when the dead zone is kept. The proper principle of flutter signal for jam diagnosis is given. Based on the given flutter signal, different jams caused by jam of the EH servo valve under different operating condition are simulated and the output of the oil pressure and actuator are presented. Meanwhile, waving threshold of the oil pressure for jam diagnosis is given. The simulations and analysis prove that the jam fault identification of the EH servo valve based on flutter signal is feasible.

When the temperature and retention time reach 160 ℃and 80 minutes respectively , most of thesolid grease in the garbage is extracted out to become floatable oil which can be separated and recovered readily. Subsequently , the amount of floatable oil begins to decrease since chemical reactions such as the partial hydrolysis of the oil take place. Additionally , the extraction of solid grease from interior accords with first2order reaction dynamic model.

结果表明，湿热处理初期，垃圾脱水率下降，加热40min 后，脱水率开始上升，且温度越高，上升越快，180 ℃加热100min 达最高；随着温度的升高和加热时间的延长，餐厨垃圾脱油性能呈上升趋势，温度越高，上升趋势越明显；当温度达到160 ℃，加热时间达80min 时，垃圾固相油脂基本浸出完全，继续升温和加热，部分油脂发生水解等化学反应，可浮油量开始降低；垃圾固相脂质浸出符合一级反应动力学。
