3 RESEARCH ACTIVITIES Master s Thesis: Semiactive Noise and Vibration Isolation for Hydraulic Hybrid Vehicles This research investigated the vibration problem of Parallel Hydraulic Hybrid Vehicles (HHV). Since the hydraulic subsystem was coupled directly to the driveshaft of the vehicle, the driveshaft became the vibration transfer path. Therefore, the powertrain of the parallel HHV was modeled in SimMechanics to investigate the vibration transmission. All the mountings were considered semiactive with controllable stiffness and damping. Appropriate configurations of mountings and connections between the hydraulic subsystem to the frame were suggested by this study. Doctoral Dissertation: A novel semiactive magnetorheological mount (MR) for vibration isolation This research is to develop a hydraulic powertrain mount (i.e. engine, transmission, pump/motor mounts) using magnetorheological (MR) fluid. This type of semiactive mounts is suitable for modern vehicles equipped with advanced technologies such as variable cylinder management or hybrids. MR fluids are smart fluids that can develop yield stress when a magnetic field is present. The MR mount employs the flow mode and the squeeze mode of the MR fluids. Each of the modes is controlled individually, so the potential contribution of each mode to the mount characteristics is maximized. The mount is designed in such a way that the operation of one mode does not interfere that of the other. The mount can operate with single modes or combined mode (or mixed-mode). These options of the operation modes allow the user to have large envelope of the stiffness and damping provided by the MR mount. One can use very high stiffness and damping to mitigate the shock loads, or various combinations of stiffness and damping for harmonic vibration isolation. Postdoctoral Research: Advanced magnetorheological (MR) fluid valve This research looks particular into reducing the amount of MR fluid used in semiactive devices. Regularly, the device is filled with MR fluid but the activated MR fluid is only within the flow channel where the electromagnet is located. In this design, the MR fluid is enclosed in a flexible pocket located inside the flow duct. When magnetic field is zero, the MR pocket is soft, and the flow (of any kind of fluids/gases) happens easily. As soon as the magnetic field is turned on, the MR pocket is hard, and the flow is restricted by the field-induced yield stress developed in the MR pocket. By varying the magnetic field strength, the flow rate is precisely controlled. That can be translated into controllable damping if this valve is used in engine mounts or shock absorbers. With small active MR fluid is enclosed in the pocket, the cost for MR fluid is significantly reduced for the MR devices. Research Projects in Graduate School: o Hydraulic Hybrid Vehicle noise and vibration test (at EPA facility in Ann Arbor, MI): This project fabricated a Hydraulic Hybrid Vehicle chassis from a Ford Expedition frame and a hydraulic subsystem including the pump/motor, accumulators and the hoses/pipes. The chassis was tested for noise and vibration characteristics of the HHV. o Hydraulic Hybrid Vehicles simulation for noise and vibration characteristics: A series HHV was modeled in Imagine.Lab (AMESim) with a simplified vehicle components and a detailed hydraulic pump/motor. The pump/motor was the main source of noise and vibration due to the pressure ripples it produced during its operation. o Shock mount designs for fuel cell in a hydrogen vehicle: The fuel cell and its mountings were modeled in simulated in SolidWorks and COSMOS for its motion response. Stiffness and damping of the shock mounts were suggested to keep the acceleration of the fuel cell within the allowable range as the vehicle ran through rough terrains. o Energy harvest using piezoelectric bimorphs: The energy harvester resembled a wind mill with a big fan blade to convert the wind power to reciprocating motion. This reciprocation provided the excitation to the piezoelectric beam. Piezoelectric beam was constructed from Macro Fiber Composites (MFC), which were piezoelectric devices. This beam bent and produced electricity while vibrating under the excitation from wind motion. o Robotic actuation using shape memory alloy: Collaborate in developing the biped robot in SimMechanics simulation and actual prototype.
