Simulations and Vibration Controls of Seat based on a Human Vibration Model
I developed a spine-protective seat to reduce RMS of acceleration by 8% and the peak of acceleration by 31% and verified the results by numerical simulation in Matlab.
• Built a high-fidelity driver-vehicle model in ADAMS with an eleven-DOF dummy body and a seven-DOF vehicle
• Ran ADAMS simulations with man and woman dummies to acquire acceleration data on specific positions under uneven road condition
• Utilized MATLAB to analyze acceleration data and verified proper stiffness and damping coefficient of the seat
• Programmed MATLAB code to conduct the numerical simulation to verify the time-solution and acquire the phase portrait.
Skills: UG NX, Adams, Matlab, Excel, Seat Design, Spine Load Analysis
