Abstract本发明公开一种用于残余应力压入测试方法检验的标准预应力加载装置,包括基体、加载元件、数显力传感器和夹具,所述基体的两端分别设置有孔,且左右两端孔同心,所述基体的内部设置有支撑试样的凸台;所述数显力传感器包括相连的力传感器和力显示器,所述力传感器设置在所述基体内部,且分别与加载元件和夹具相连;所述加载元件通过所述基体左端的孔与所述力传感器相连,用于对试样施加轴向的压力或拉力;所述夹具位于所述基体内部,用于将试样沿轴向夹紧,并通过基体右端的孔与基体固定。本发明的装置结构简单,预应力分布均匀、测量直接准确,且在压入测试过程中,预应力状态稳定,其值不受压入实验影响,因此可作为一种标准预应力产生装置使用。
