摘　　要：在小扰动假设前提下，采用迭加和差分概念相结合的算法，首次求得可变节流动静压混合轴承的八个动特性系数；计算过程中考虑了可变节流器的容积变化。与此同时，还分析计算了固定节流轴承的动特性，并将两种节流方式下的结果进行了比较，为以后的稳定性研究打下基础．Eight dynamic coefficients of hybrid journal bearing compensated by a variable restrictor are given at the first time, using a technique combining the finite difference concept method with the superposition method on disturbance condition.The volume variation of the variable restrictor is concerned during the computation.The dynamic characteristics of the bearing with fixed restrictor are also discused in the meantime.The results of this two restrictors are compared,which provide the basis for later investigation on stability.
