Fluid Coupling Hydrodynamic Calculation Method And Simulation On The Combined Working Characteristic

Hydrodynamic-drive element mostly comprise fluid coupling and hydrodynamic torque converter, for their particular performance , they are widely applied to lots of scopes such as engineering mechanisms,high-power pumps and fans,the startup of over loading equipment and so on. Recent years, they are used in some aspects combustion turbine's startup,the drive unit of wind turbine generator, for instance, even in flight refueling,the holding up of carrier-borne aircraft.In my paper, I give emphasis to the research of fluid coupling's hydraulic design technique. Compared to hydrodynamic torque converter, the fluid couplings we usually use in project are no guide ring, oared interval channel is only part of structural channel, in the situations of cavity is partially brimmed, there are not determined boundary condition in channel, liquid is in the situation of no pressure, it is hard to do some numeration. So far, in the engineering design of fluid coupling, the numeration of similitude is generally applied, in primary design it is hard to avoid blindness, and also requiring that factories and the branches of design have accumulated some types of excellent hydraulic models and prior knowledge about performances. In my paper, I am on the basis of the measures of fluid coupling's hydraulic design technique which have existed, in the light of the theory of one dimensional beam flux, summarize the numeration of hydraulic about fluid coupling. As a result, through hydraulic computation, integrating the design of similitude, the numeration about characteristic structural parameters of fluid coupling's circulating circle can get upstanding result.The analysis about the transfer characteristic of fluid coupling working with power machine is also important part of fluid coupling's design about matching. In the paper, in the light of the mathematical model of electromotor,element's primitive character and the working performance of load, I introduce the measure of emulate about characteristic performance working together.
