摘要

加工了拉伸 – 剪切复合载荷的测试装置，并开展了钛合金螺栓在纯拉伸、纯剪切、拉伸 – 剪切耦合等受力状态下的力学试验，分析了拉应力与螺栓轴线角度变化对试验结果的影响及其相应变化的规律。研究结果表明，一是加工的拉伸 – 剪切复合载荷的测试装置可以准确满足纯拉伸、纯剪切、拉伸 – 剪切等单一载荷与复合载荷不同受力状态的力学性能测试；二是钛合金螺栓在拉应力和切应力耦合作用下的力学性能指标较纯拉性能明显下降，降幅最高达 40%。

Abstract

A testing device for tension–shear combined load was processed

and mechanical properties tests were carried out under pure tension

pure shear

tension–shear combined load. The influence of tensile stress and bolt axis angle on the test results and the corresponding variation law were analyzed. The results show that the mechanical properties of titanium alloy bolts under the tensile and shear combined load are obviously lower than those under pure tensile load

with a maximum decrease of 40%.
