摘　　要：重点介绍了压裂泵泵头体在同一内压作用下,各处发生的塑性变形和产生的残余应力的大小是不一样的,利用ANSAYS软件试算的方法确定泵头体的弹性极限压力,获得了泵头体在小于弹性极限内压的压力作用下的有限元弹性模拟模型,从而发现压裂泵泵头体的危险部位在缸腔和阀腔相贯部位,能够很好地解释现场发生的泵头体开裂现象。Focusing on the body in the same fracturing pump head under internal pressure, plastic deformation occurred throughout the residual stress and the size is not the same, the use of spreadsheet software ANSAYS method to determine the elastic limit pressure pump head body , won the pump head body is less than the elastic limit pressure in the pressure under the action of elastic finite element simulation model, which found the risk of fracturing pump head body parts in the cylinder chamber and valve chamber intersecting parts, this result can he very good site to explain the occurrence of the pump head body cracking phenomenon.
