简介:对在有JP-8+100喷气发动机燃料和Mil-L-23699涡轮喷气发动机油的情况下工作的钢和陶瓷(氮化硅)材料的摩擦系数、轴承性能(即力矩产生和温升)及滚动接触疲劳进行了试验。使用球对盘试验机,测量在不同载荷和滑滚比下,用JP-8+100喷气发动机燃料润滑时,运转的钢球对钢盘的摩擦系数。结果表明,在这个试验设想的条件下,燃料提供极低的摩擦系数。使用三球对拉杆滚动接触疲劳试验机测定材料(即氮化硅和钢材)和润滑油不同组合的疲劳寿命。像期盼的那样,Weibull分析表明在有喷气发动机燃料情况下运转的滚动疲劳寿命小于油润滑接触的。也设计、研制了轴承试验机,并用其获得在喷气发动机燃料和油中运转的轴承的摩擦(力矩)和温度性能。轴承试验结果表明燃料比油产生的力矩和温升低。
