单边直线感应电机(SLIM)因结构简单牢固,直接产生前进的电磁推力,在交通中得到广泛应用。 由于其磁路断续,电机运行中存在横向和纵向边缘效应;次级的入口和出口因气隙磁链守恒原理会产生涡流, 并随速度上升而加大。边缘效应和涡流大小对直线电机气隙磁链产生重要影响,造成气隙有效磁通和牵引力系 数降低。探讨直线电机工作特点,得到了电机d-q轴等效电路,通过d轴互感和电阻变化来实时反应第二纵 向边缘效应和次级涡流的影响。结合旋转电机转子磁场矢量控制方法,建立了对应的SLIM控制方程。采用转子 磁链、速度和电流三个调节器,提出了uds,uqs,iqs实时在线解耦补偿控制方法,对SLIM的推力、d-q轴电压、d-q轴磁链等进行调节和控制,对d轴互感大小进行限制。结果表明,该方法在电机速度突变时减小了力 矩脉动,定子电流过渡平滑,速度平稳,改善了SLIM的运行性能,为电机实际运行分析提供了理论依据。

Novel casting processes for single-crystal turbine blades of superalloys

《机械工程前沿(英文)》 2018年 第13卷 第1期 页码 3-16 doi: 10.1007/s11465-018-0475-0
This paper presents a brief review of the current casting techniques for single-crystal (SC) blades, as well as an analysis of the solidification process in complex turbine blades. A series of novel casting methods based on the Bridgman process were presented to illustrate the development in the production of SC blades from superalloys. The grain continuator and the heat conductor techniques were developed to remove geometry-related grain defects. In these techniques, the heat barrier that hinders lateral SC growth from the blade airfoil into the extremities of the platform is minimized. The parallel heating and cooling system was developed to achieve symmetric thermal conditions for SC solidification in blade clusters, thus considerably decreasing the negative shadow effect and its related defects in the current Bridgman process. The dipping and heaving technique, in which thin-shell molds are utilized, was developed to enable the establishment of a high temperature gradient for SC growth and the freckle-free solidification of superalloy castings. Moreover, by applying the targeted cooling and heating technique, a novel concept for the three-dimensional and precise control of SC growth, a proper thermal arrangement may be dynamically established for the microscopic control of SC growth in the critical areas of large industrial gas turbine blades.

《机械工程前沿(英文)》 2006年 第1卷 第1期 页码 21-25 doi: 10.1007/s11465-005-0018-3
To design various optimum parameters and simulate the working process of CP single-screw compressor, the Computer-Aided Design (CAD) system for the CP single-screw compressor has been established. A new method based on computer graphics technology, database technology, object-oriented programming technology, and visual simulation technology has been adopted in this CAD system. The system has integrated solid modeling function with parameterization design function and animator simulation function based on analyzing the working principle of the CP single-screw compressor. The experimental results show that the CAD system for the CP single-screw compressor is practical and feasible.
