为了研究柱塞泵十字头的疲劳强度,在有限元的基础上,根据古德曼法和应力寿命法对十字头进行了疲劳强度分析,经十字头的实际应用验证可知,对十字头的疲劳寿命分析是正确的。
In order to study the fatigue strength of the plunger crosshead, the fatigue strength of the crosshead was analyzed based on the finite element method and the Goodman method and the stress life method. The crosshead fatigue test Life analysis is correct.
