Abstract:Effects of working parameters on performance characteristics of hydrostatic turntable are researched by applying the fluid-structure-thermal coupled model. Fluid-structure interaction (FSI) technique and computational fluid dynamics (CFD) method are both employed by this new model, and thermal effects are also considered. Hydrostatic turntable systems with a series of oil supply pressures, various oil recess depth and several surface roughness parameters are studied. Performance parameters, such as turntable displacement, system flow rate, temperature rise of lubrication, stiffness and damping coefficients, are derived from different working parameters (rotational speed of turntable and exerted external load) of the hydrostatic turntable. Numerical results obtained from this FSI-thermal model are presented and discussed, and theoretical predictions are in good agreement with the experimental data. Therefore, this developed model is a very useful tool for studying hydrostatic turntables. The calculation results show that in order to obtain better performance, a rational selection of the design parameters is essential.
