摘要
根据Ｍ．Ｍ．Ｋｈａｓａｎｏｗ所建立的涡轮枢轴非线性震动的数学模型，利用当前非线性科学领域的研究成果，进一步给出了钻柱振动失稳尖点的突变模型。并求得了发生失稳的临界点和条件，对揭示钻井过程中动力失稳的现象具有一定的参考价值。
On the basis of mathematical model developed by M. M.Khasanow for nonlinearvibration of turbine poivot.a mathematical model for catastrophe point of vibration bucklingof drill ing strilling was proposed.The critical catastrophe pointo of buckling weredetermined.The conditions of losing stability for drillstring vibration were given.
