Obtaining Modelling Parameters for SimHydraulic Components

Hi,

I would like to know how do people typically obtain parameters for their SimHydraulics models? I would like to model systems using off-the-shelf components but many of the SimHydraulic parameters don't seem to be supplied by manufacturers as standard.

For example, the Pressure Relief Valve block requires parameters such as Maximum Passage Area, Valve Leakage Area, Flow Discharge Coefficient & Regulation Range. I've looked through quite a few data sheets from manufacturers such as Bosch Rexroth, Eaton and Parker; but none of these supply the required parameters.

So I've been left wondering how I can obtain realistic values for these parameters...

I would be grateful if anyone has any input to this.

Thanks, Darren

Hello,

I have the same problem. I coudnt find out the parameters for my valves neither for the pump. concerning the valves, there is a vedio for how to tune tha parameters if you have have a chart and want to follow it. look at it, it may help you. although it didnt help me.
