立式主轴综合加载疲劳试验器4BSQ32就是用来确定涡喷和涡桨发动机主轴疲劳寿命的试验装置。它是我公司在臥式涡轮轴试验器4BSQ7长期使用经验的基础上设计的。它通过外载荷模拟,边界条件模拟及温度模拟可对中型航空涡轮发动机主轴作疲劳寿命试验,包括对该类型双转子主轴进行疲劳寿命试验,也可对同类主轴进行极限静强度,届服强度和刚度验证试验。在试验器设计方案方面,为避免自重引起横向弯矩,采用了立式布置;为克服用偏
Vertical spindle integrated loading fatigue tester 4BSQ32 is used to determine the vortex spray and turboprop engine spindle fatigue life test device. It is based on our long-term experience with 4BSQ7, a horizontal turbine shaft tester. It can be used to test the fatigue life of the mid-size aero-turbine engine spindles by external load simulation, boundary condition simulation and temperature simulation, including the fatigue life test of this kind of double-rotor spindles, the ultimate static strength, Stiffness verification test. In the design of the tester, in order to avoid the transverse bending moment due to its own weight, a vertical layout was adopted.
