摘　　要：在应用影响系数法对简支梁进行计算的基础上推出广义影响系数法 ,在考虑支承与集中质量相距为任意长度以及轴系在弹性支承的工况下 ,编制相应的广义影响系数法的计算机程序 ,对自行设计的“多功能模拟轴系试验台”(已申请专利 )的各转子进行设计计算 ,并用有限元法。Generalized influence coefficient method is deduced, which is based on calculation on simply supported beam by applying influence coefficient method. A reasonable calculating model was established. Also, using formula of material mechanics calculating deflection, and considering the influence caused by random length away from support and concentrated mass and by elastic support as well as the influence caused by distribution un-symmetry of concentrated mass, we get influence coefficient, then applied frequency equation of multi-freedom system by numerical value calculating method in order to obtain critical speed of multi-freedom system and corresponding mode. Using computer Visual C language, we compiled the computer programs of the generalized influence method. Calculation on each rotor of 'the self-designed multifunctional turbogenerator Simulating shafting test set' (applied for patent) is processed by the way, and by using the finite element method and the transfer matrix method and using mode test.
