Low thrust,high force ripple and low regenerative efficiency are the major disadvantages of the electromagnetic active suspension.The design method of a high thrust.low force ripple and high regenerative efficiency actuator is investigated in this paper.Using Halbach permanent magnet array,an analysis model of actuator is built.A quantitative analysis for local sensitivity of parameters is established based on modified Morris method.For the distribution of gap magnetic field and induced electromotive force(induced EMF),the parameter of permanent magnet and flute profile has been optimized.The method of increasing end thickness is employed to decrease the ripple.After optimization,the energy-regenerative ability,electromagnetic force(EM force)and the force ripple have been improved a lot.Finally,the parameters matching calculation of EM force and active force have been validated which indicates that this actuator satisfies requirements for active suspension.

全球气候变暖同时引起白天和夜间温度升高。我国水稻在高温敏感期(幼穗分化期、抽穗开花期、灌浆期)遭受夏季高温热害的可能性越来越高。而高温对水稻生长发育影响的研究多数集中于白天高温,夜间高温下水稻的响应及基因型差异的研究还较少。水稻生长中、后期高温主要通过影响穗粒数和结实率而显著降低籽粒产量,然而其机理还不清楚。本研究以耐热性品种(汕优63、T226、N22)和热敏感品种(两优培九、T219、IR64
