Random vibration analysis and parameter optimization

Random vibration caused by the base excitation is a very common environment to many products, especially to those mounted on a vehicle. Two fundamental vibration models, single-degree-of-freedom (SDOF) and two-degree-of-freedom (TDOF) systems, are investigated for their reliability against the acceleration failure in this paper. The optimum parameters of the vibratory systems are researched to maximize the reliability. The proposed procedure is illustrated by two numerical examples
