Simulation of Electrohydraulic Power Systems

Join us for this webinar to learn about simulating electrohydraulic power systems, featuring guest speaker Steven (Feng) Qi from FZB Technology. In the presentation, he will discuss a multiphysics model of the latest pump design for automotive applications from FZB's team.

Electrohydraulic power steering (EHPS) is a very fuel-efficient technology for steering systems. One of the key components is the hydraulic pump, which is powered by an electric-controlled motor, while the fluid interacts with the steering gears to add extra torque. The modeling of EHPS systems is therefore multiphysics by nature. FZB's team modeled the major components of their EHPS system, including the electronic control unit (ECU), motor, helical gear pump, mounting bracket with isolators, as well as the entire system assembly.

Steven will discuss the approach used for the thermal-mechanical analysis of FZB's EHPS design to ensure a safe operating temperature range. He will also present an electromagnetic model for the helical magnet feature to reduce ripple torque and a helical gear pump and its coupling to CFD and acoustics.

The webinar includes a live demo in the COMSOL Multiphysics® software and a Q&A session.
