Dynamic Characteristics Analysis of Suspending System in Static Balancing Machine forMarine Propeller

摘要

The paper deals with a fully hydraulic static balance machine for huge marine propeller, which uses large-scale hydraulic spherical bearing to suspend propeller measured. The mathematics model of suspending system in static balance machine is set up, the nonlinear differential equations of the system is derived. Two kinds of situations of the supporting collet are considered for the elasticity deformation and no elasticity deformation. Then, analysis of the dynamic characteristics is done with the changes of the supply pressure, load, structural parameters of spherical hydrostatic bearing and the effective bulk modulus of oil. Finally, some conclusions are drawn, which has an important significance to the design of fully hydraulic static balance machine.
