Abstract
Content
This paper describes methods to reduce body shake caused by engine vibration at idling from the viewpoint of body structure through the control of resonant frequency and shake modes.
  1. (1)
    Resonant frequency control method; Optimization of stiffness versus body member mass affected by large strain or kinetic energy is essential to control resonant frequency. Resonant frequency can be shifted in conjunction with the ratio of energy on a member to whole body energy.
  2. (2)
    Body shake reduction method; Optimized distribution of stiffness throughout the body produces a favorable body shake mode and minimizes shake levels at relevant parts of the body such as the steering column support and floor while counterbalancing high shake levels in other parts of the body.
