For machine structures which are exposed to hard working conditions, for example, those of construction machinery, and offroad-type vehicles, maintenance schemes that allow longer operating life are becoming more imporant in the attempt to improve productivity and reduce maintenance cost. We propose several algorithms for a nearly real-time monitoring system on operating machines, which predicts strain responses and damage at evaluation points based on strain modal analysis without measurement of strain meters. This paper introduces applications of these methods for offroad-type dump trucks. The validity of the method, which uses four measured suspension forces for driving on uneven road and transfer functions about strain on the main frame, is demonstrated through comparison with measured strain responses.
