摘要： A system and method of controlling engine vibration mounted within a vehicle including at least one hydraulic mount, each mount including a fluid chamber. A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a relative acceleration signal. A control unit is electrically connected to the accelerometers. The control unit is adapted to generate an electronic control signal in response to the relative acceleration signal. The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount. A control algorithm calibrates the control unit such that maximum vibration damping occurs at and around the engine resonance bounce frequency.

摘要： A magnetorheological-fluid hydraulic mount includes a hydraulic-mount partition plate assembly, a hydraulic-mount decoupler, an electric coil, and a flexible membrane assembly. The partition plate assembly has first and second sides, has a non-magnetorheological-fluid first orifice, and has a magnetorheological-fluid second orifice. The first orifice has a first terminus positioned at the first side and a second terminus positioned at the second side. The second orifice has a first end positioned at the first side and has a second end positioned at the second side. The hydraulic-mount decoupler is operatively connected to the first orifice. The electric coil is disposed to magnetically influence the second orifice. The flexible membrane assembly has a first membrane portion fluidly-isolating, on the first side of the partition plate assembly, the first end from the first terminus and has a second membrane portion fluidly-isolating, on the second side of the partition plate assembly, the second end from the second terminus.

摘要： In July of 2004 KTH Racing will attend at the Formula Student event in England. The Formula Student event is a competition between schools that has built their own formula style race cars according to the Formula SAE rules. In January of 2004 the Formula Student project started at KTH involving over seventy students. The aim of this thesis work is to design the suspension and steering geometry for the race car being built. The design shall meet the demands caused by the different events in the competition. The design presented here will then be implemented into the chassis being built by students participating in the project. Results from this thesis work shows that the most suitible design of the suspension is a classical unequal length double A-arm design. This suspension type is easy to design and meets all demands. This thesis work is written in such a way that it can be used as a guidebook when designing the suspension and steering geometries of future Formula Student projects at KTH.

摘要： A powertrain mount comprises an orifice plate including two tracks, a control track and an isolation track. The control track is spirally formed within the orifice plate, which has an exit and entrance on either side of the plate. The control track provides damping to control damping from engine bounce; whereas, the isolation track controllably provides dynamic rate dip. The isolation track is formed between an alignment plate and rotatable track member, each having an exit and entrance, respectively. The rotatable track member and the alignment plate are sealingly engaged and affixed to a decoupler and an annular area disposed about the orifice plate of the powertrain mount. The exit of the alignment plate is adjacent the decoupler. The rotatable track member forms a cavity with the molded body of the powertrain mount, with the entrance exposed to fluid within the cavity for controlling and minimizing vibrations within the powertrain. The isolation track has a track length that may be varied by rotation of the track member and its entrance. Various magnitudes of disturbance frequencies may be managed and controlled by either the fixed control track and/or the variable isolation track within the powertrain mount.

摘要： A hydraulic mount having first and second fluid tracks, and a decoupler functioning as an air spring with two remotely selectable settings. The settings allow tailoring of the air spring characteristics to provide mount damping for differing engine operating states, such as engine idle. A solenoid is used to select a smaller or larger air volume to control the characteristics of the air spring and, in turn, the dynamic response of the hydraulic mount. An integral controller provides switched operation of the solenoid and compensates for variations in temperature and input voltage, as well as minimizing electrical noise generated by the solenoid when it is energized.

摘要： An active vibration control device for controlling vibration in a cantilevered member and a method for the same are disclosed. The device is comprised of a cantilevered member having a longitudinal axis comprising a sensor mounted near the free end of the member to measure motion of the member in a transverse direction and to produce a corresponding signal. A force generating assembly is mounted to the member near the free end to oppose the measured motion with a force thereby minimizing subsequent motion along the transverse axis caused by vibration.
