摘　　要：针对金属细管在拉伸、扭转试验中易从夹持处断裂和弯曲试验中易瘪的问题,对其拉伸、弯曲和扭转力学性能在试验原理、尺寸测量、试验速度、夹具设计等方面进行了系统研究。通过对大量试验进行分析比较后,解决了金属细管拉伸、弯曲和扭转试验中一些试验技术问题,并对试验方法进行了归纳总结,推导了计算金属细管弯曲试验结果的数学表达式。For the problems that the metallic tube torsion tests and easy to deflated in bending tests, test speed and the fixture design on its tensile, is easy to break at the clamp in tensile or the test principle, dimensional measurement, experiments were systematically investigated. Through bending and torsion mechanical properties analyzing and comparing large number of experimental results, some test technical problems for metallic tubes in tensile, bending and torsion experiments were solved. Finally, this paper summarized the test methods and deduced the mathematical expression used to calculate the bending experiment results of metallic tubes.
