The digital simulation of thedynamic processes under step load input and supply oil pressure fluctuation were carried on by MATLAB. Analysis of the dynamic characteristics was done with the changes of the supply pressure, load, structural parameters of spherical hydrostatic bearing and the effective bulk modulus of oil. The conclusions show that structural parameters of the spherical bearing and the effect bulk modulus of oil have significant influence to dynamic characteristics, but the elasticity deformation of interior supporting collet has very small influences on the output response characteristics of the suspension system. The collets deformation can be neglected on the project.
