【Abstract】 This paper describes the method of vibration measurement and analysis for the seat of J-50 tractor. Through measuring self-power spectrum and transfer function of the seat and place to hang the seat, dynamic characteristic of the tractor seat is analysed. The index and standard of evaluating riding comfort are introduced briefly in this, paper. Riding comfort is evaluated for the seat, making use of evaluated method recommended by ISO2631(fatigue-decreased,proficiency boundary). The result makes known, riding comfort of the seat want to be improved further for J-50 tractor.更多还原
