    摘要:

    在分析永磁式渦流緩速器制動力矩與結(jié)構(gòu)參數(shù)關系的基礎上，將均勻設計和回歸分析方法引入到永磁式渦流緩速器制動性能影響因素敏感性分析中。以某型號的永磁式渦流緩速器為例，建立了制動力矩隨轉(zhuǎn)子鼓內(nèi)半徑、永磁體周向長度、氣隙寬度、轉(zhuǎn)子鼓軸向?qū)挾群陀来朋w高度5個結(jié)構(gòu)參數(shù)變化的回歸模型，重點討論了結(jié)構(gòu)參數(shù)間交互作用以及各結(jié)構(gòu)參數(shù)對制動力矩的影響程度，基于均勻試驗設計和制動性能敏感性分析的結(jié)果，采用全排列法對結(jié)構(gòu)參數(shù)進行了優(yōu)化。

    Abstract:

    Based on the relationship between braking performance of permanent magnet type eddy current retarder and structure parameters, the method of uniform design and regression analysis were applied to sensitivity analysis on influence factors for braking performance of permanent magnet type eddy current retarder. The regressive models of braking torque were established concerning inside radius of rotor, circumferential length of permanent magnet, width of air-gap, axial width of rotor influenced and height of permanent magnet, the influences of structure parameters and it’s interaction of permanent magnet type eddy current retarder on braking performance were studied systematically. Based on the result of uniform experimental design and sensitivity analysis, structure parameters were optimized by means of whole-arrangement method. The conclusion can be used in the option design, enhance braking torque and improved braking performance of permanent magnet type eddy current retarder. 
