摘要
本文从振动疲劳强度角度分析拖拉机驾驶室的结构和受力特点,找出了疲劳强度薄弱的部位,从理论上估算的该部位疲劳寿命与试验结果接近.
Structure and loading characteristics in tractor cabs are studied in the light of vibration fatigue strength and the location of low fatigue strength in the parts is found. Its fatigue life are calculated and the calculated results in agreement with measured ones.
