Lumbar Resonance

Lukas Korn, Salman Muhammad, Mechanical Engineering, Kennesaw State University 1000 Chastain Rd, Kennesaw, GA 30144, United States

The goal of this lab is to find the damping coefficient and stiffness of a mannequin’s lumbar region. This information will lead to the finding of the resonance frequency of the human back. This frequency is critical information in designing better technology for humans in the future because a system could cause serious damage to tissue and bone structure if operated at the resonance frequency of the human lumbar region. To accomplish the goal the resonance method will be used. A vibrating motor is placed on the mannequin’s back. This motor will have an accelometer attached as a reference point. Two other accelometers will be placed on the L2 and L4 back region. These accelometers will be measured relative to the motor’s acceleration. From this data the natural frequency, damping coefficient, and stiffness will be calculated.
