【摘要】：根據(jù)航空發(fā)動(dòng)機(jī)推力銷的工作特性和受力建立其有限元模型,利用ANSYS軟件的APDL語言編寫參數(shù)化的結(jié)構(gòu)應(yīng)力有限元分析程序,并利用地面校準(zhǔn)加載試驗(yàn)驗(yàn)證了計(jì)算結(jié)果的準(zhǔn)確性。利用自編程序計(jì)算推力銷在全飛行包線下的力學(xué)響應(yīng),并選取合理的安全系數(shù),繪制出推力銷的強(qiáng)度包線。對強(qiáng)度包線和工作包線的分析表明,推力銷的工作包線被完全包絡(luò)在強(qiáng)度包線內(nèi),結(jié)構(gòu)強(qiáng)度滿足重復(fù)測量的要求。
[Abstract]:The finite element model of thrust pin of aeroengine is established according to its working characteristics and force, and the parameterized finite element analysis program of structural stress is compiled by APDL language of ANSYS software. The accuracy of the calculation results is verified by the ground calibration loading test. The mechanical response of the thrust pin under the full flight envelope is calculated by using a self-compiled program, and a reasonable safety factor is selected. The strength envelope of the thrust pin is drawn. The analysis of the strength envelope and the working envelope shows that the working envelope of the thrust pin is completely enveloped in the strength envelope and the structural strength meets the requirements of repeated measurement.
