A Methodology for Vibration Measurements in Lawnmowers Engines 2006-01-2589

TMT-Motoco do Brasil is an enterprise from Tecumseh Group. TMT develops lawnmowers, lawn trimmers and walk behind mowers engines. The present work has a purpose to present a methodology for vibration measuring in such particular engines. There is no work in Brazilian literature related to such kind of engines and that is the main reason for this paper. The actual methodology presents a detailed procedure to evaluate engine vibration, trough spectra measurements, order analysis and signature analysis and how to design an experiment to evaluate engine vibration. Through order analysis, engines were tested in current applications (walk behind mowers) and test stands to obtain frequency responses. Such experiments are the initial part of a larger analysis of vibroacoustic behavior of mowers engines.
