摘　　要：通过对实验原理进行理论分析, 采用Fortran, Matlab软件对实验进行数值模拟仿真, 利用仿真对比分析实验中出现的压力有肩、位移飘动以及压力位移曲线存在相位差等现象。The occurrence of time-dependent cavitation and the tensile stress in an oscillatory oil squeeze film were investigated experimentally for isolating the shearing movement and standing out the squeezing movement of journal bearing,and the simulation of the squeeze film experiment was accomplished by compiling Matlab and Fortran computer programs.The results of the simulation were discussed to analyze the curve phase and distribution of pressure and displacement curve.
