<p>PROBLEM TO BE SOLVED: To know which device among devices arranged in a three-dimensional space composed of a structure, a fluid, and a base, is increased in vibration or noise, to make the life possible to judged by comparing vibrations and noises of multiple plants, and to suppress the increase in cost therefor. SOLUTION: To vibration and noise analyzing software based upon a statistical energy analysis method, a function of reverse analysis of the power of vibration and noise sources from measured vibration and noise values, and analysis of the degree of contribution of the vibration and noise sources to the vibration and noise, and evaluation points of the whole system is added, and the vibration and noised computed values of the evaluation points are compared with permissible values so as to decide whether the operation conditions need to be changed and supply data on whether the operation conditions need to be changed. Further, plants are managed centrally via the Internet and the life time of devices is decided by comparing the history data on the degree of contribution to the vibrations and noises of the respective devices of the respective plants.</p> |
