【Abstract]To improve the massage eficacyof electric vehicle massage seats，this paper proposes an evaluation method basedon theanalysisof time-frequencydomaincharacteristicsof surface Electromyography（sEMG）signals.Firstly electromyographicsignalsarecolectedfromthetrapezus，lower trapezius，latissimusdorsianderectorspinae musclesunder three distinct states：comfort，fatigue，and massage，thenthosesEMGsignalsarepreprocessed through filteringand normalization，folowed bytheextractionof MedianFrequency（MDF）andRoot Mean Square（RMS）features.Characteristic difference of the sEMG features among the three states （ P<0.05 ）is compared，which confirms validity of the proposed evaluation method.Furthermore，theanalysisofmusclerelaxationacross diferent muscle groupsprovides insights into the optimization of the mechanical massage structure.
