Computer Aided Analysis System for Noise and Vibration on Vehicles

An analysis system for vehicle noise and vibration has been developed. It consists of minicomputer based analog processing system connected with a large main-frame computer. This system features multi-modes for data analysis, fast data processing, data compatibility with conventional analog systems and feasibility. Fast data processing was achieved by newly developed FFT processor and minicomputer software. A new remote control box makes it simple to operate. Data processed by the minicomputer can be transferred to a large mainframe computer for further analysis.
