摘要/Abstract

摘要： 为提高朗肯循环中膨胀机的密封性能及功率密度，设计了一种交叉斜盘式功率传输机构来消除活塞与气缸之间的侧向力。建立了交叉斜盘机构的数学模型，分析了机构直线驱动活塞原理及高功率密度实现原理。在此基础上，建立缸内热力学模型，分析缸内气压随主轴转角的关系，并进行了数值计算和仿真分析。通过分析交叉斜盘机构传动过程中的摩擦损耗，研究了机构功率传输特性，进行了气动及电机拖动实验，实验结果与仿真结果基本一致。

Abstract: As a way to increase power density and sealing performance of expander used in Rankine cycle, a crossed swash-plate mechanism which could eliminate lateral forces between piston and cylinder was proposed. A mathematical model was established to analyze the theory of linear driving and high-power density. Then a thermodynamics model was built to analyze the pressure curves in cylinder varying with rotated angle of shaft, numerical experiments and corresponding simulation were carried out. By the means of investigating friction loss in transmission of crossed swash-plates, power transmission characteristics were studied. The experiments which power prototype by gas and motor were completed. Experimental results correspond to the simulation ones well.

Key words: swash-plate mechanism, high compact, dynamics characteristics, Rankine cycle
