In the buckling question under nonconservation force, a simply example ( the dynamic stability question under the uniformly follower forces with small deformation % linear elastic, straight normal. ) is considered. the variational equation of braid composite cylindrical shells subjectd to uniformly follower forces is deduced based on the variation principle of quasinatural frequency of elastic nonconservative system self - excited vibration. the calculated formulas of the flutter load and quasinatural frequency of shells are obtained. the program for calculating the flutter load is developed. the numerical example is given and some useful conclusions are obtained
對非保守力作用下的屈曲問題,具體研究了圓柱殼在比較簡單的情況,即小變形、線彈性、直法線假設下在隨動力作用下的殼屈曲問題,由擬固有頻率變分原理推出了圓柱殼受隨從力作用的變分方程,得到了顫振載荷與殼彎曲的固有頻率的計算公式,編制了相應的計算機程序,並給出了具體算例,得到了一些有益的結論。The flows in the case of different reduced frequencies are computed respectively for two blade profiles. by comparing the time curves of relative parameters in oscillating cascades and the flow field contours under different conditions, it is indicated that the reduced frequency is an important factor to determine whether the blade flutter happens or not
針對兩種葉型分別計算了不同摺合頻率下的流場,通過比較振動葉柵相關參數隨時間變化的曲線及流場雲圖,表明摺合頻率是決定葉片顫振與否的重要因素。
