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.

在此基础上，建立了考虑内支撑筒的弹性变形与否时悬浮系统的数学模型，同时，建立了线性化的仿真模型，利用MATLAB对阶跃负载输入和油源压力脉动输入下的系统进行动态过程的数值仿真，结果表明球面副的结构参数，油液的有效体积弹性模数对系统的响应特性有明显的影响，而内支撑筒的弹性变形对悬浮系统的响应特性的影响很小，在工程上可以忽略其弹性变形。
