A solenoid-based active hydraulic engine mount: modelling, analysis, and verification

The focus of this thesis is on the design, modelling, identification, simulation, and experimental verification of a low-cost solenoid-based active hydraulic engine mount. To build an active engine mount, a commercial On-Off solenoid is modified to be used as an actuator and it is embedded inside a hydraulic engine mount. The hydraulic engine mount is modelled and tested, solenoid actuator is modelled and identified, and finally the models were integrated to obtain the analytical model of the active hydraulic mount. Then the active mount is tested and showed that the analytical model can closely predict its behaviour. In future, the developed model can be used for designing the vibration control system of this active mount. This active mount can potentially work as part of an active noise and vibration control (ANVC) system in automotive or other closely related applications as an alternative to more expensive active mount systems.
