| 摘 要： | 对GTCP131-9A辅助动力装置（APU）性能参数（排气温度和燃油流量）换算公式展开研究。提出了一种研究燃气轮机相似性的通用方法。采用这种方法得出了构成该单转子定轴燃气轮机相似的充分条件是需要有3个相互独立的相似准则数相等,这3个相似准则数可以是飞行马赫数、折合转速、折合功率,其他相似参数是这3个相似准则数的函数。根据该发动机相似性,采用小偏差法,给出了试车过程中存在的排气附加阻力、燃油热值偏差和功率偏差的性能参数的小偏差修正方程。结果表明:在输出功率和大气压力比值为定值的条件下,GTCP131-9A辅助动力装置性能参数换算公式是进气总温多项式与排气附加阻力修正项、燃油热值变化修正项、功率变化修正项之和。

| Abstract: | In order to study the vibration and noise of the induction motor under practical working conditions, a database of magnetization and magnetostrictive curves of silicon steel under different harmonic excitations was tested. Based on the measured constitutive relations, an electromagnetomechanical coupled numerical model for the motor core was presented. Considering the electromagnetic force and magnetostriction effect of silicon steel, the magnetic field and mechanical field were calculated for the induction motor. The distribution of the magnetic flux density, stress and vibration of the motor were obtained from the calculation. And the influence of different harmonics on the vibration was analyzed, which provided the theoretical basis for vibration and noise reduction of induction motors. |
