Latest Patents
One of his latest patents is titled "Method of designing magnetorheological fluid energy absorbing device using hydromechanical analysis." This patent provides a method for designing a magnetorheological (MR) fluid energy absorbing damper using hydromechanical analysis with lumped parameters. This approach allows for the determination of whether a potential damper design will meet predetermined characteristics, such as a desired dynamic force range and maximum piston velocity, with a selected MR fluid and yield stress, while also adhering to specific geometric limitations.
Another significant patent is the "Bi-fold valve-type magnetorheological fluid energy absorbing device." This invention includes a damper assembly with inner and outer concentric tubes and a piston that moves within the inner tube. The design forms bi-fold valve-type cavities that connect the inner chamber of the inner tube with an outer chamber formed between the inner and outer tubes. The device is filled with magnetorheological fluid, which contains coated magnetic particles at about 10 to 60 percent by volume. Electrical coils adjacent to the bi-fold valves can be selectively energized, allowing the energy absorbing device to provide a tunable damping force, particularly beneficial in automotive applications.
