摘　　要：为了研究拧紧力矩和预紧力之间的关系,以基体材料为Ti-6Al-4V、表面喷涂铝处理的钛合金紧固件作为研究对象,通过分组试验研究不同拧紧方式、润滑方式、拧入次数、不同温湿度条件下的拧紧力矩与预紧力的关系。研究结果表明:在拧紧方式、润滑方式不同条件下K值差异较大;拧紧次数对拧紧力矩影响不定;低温高湿环境下力矩相对减小,高温低湿环境下力矩相对增大。In order to study the relationship between tightening torque and pre-tightening force,titanium alloy fasteners with Ti-6Al-4V matrix material and aluminum sprayed surface treatment were taken as the research object to study the relationship between tightening torque and pre-tightening force by different tightening and lubrication methods,in number of tightening times and in different temperatures and humidities.The research results indicate that there are significant differences in K values with different tightening and lubrication methods,the influence of tightening times on tightening torque is indefinite.And the torque decreases relatively in low temperature and high humidity environments,but increases relatively in high temperature and low humidity environments.
