Signal Processing as a Tool to Enhance Productivity in Industry Measurement and Cancelation of Periodic Signals

Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

Sammanfattning: Preface This licentiate thesis summarizes my work within the field of Signal Processing during my time in Signal Control Sweden AB from 1987 to 2002. The work has been performed in close co-operation the customers like Volvo Personvagnar AB, Sveriges Provnings- och forskningsinstitut and others. Most of the material has been published at various conferences together with the Department of Signal Processing at Blekinge Institute of Technology. However, here I have had the opportunity to expand the text to give a more thorough description of the algorithms that have been designed. The thesis consists of five parts, which are: Part I An Order Analysis Method for Interior Noise Measurements in Cars Based on a Virtual Tachometer. II A Fast Multi-plane Shaft Balancing Method for 4-Wheel Drive Cars. III Custom Designed Filters through Time-Window Modification. IV Active Vibration Control of Cutting Operations. V Adaptive Vibration Control of a Large Dimension Carbon Fiber Boring Bar.
