MULTI–INPUT MULTI–OUTPUT VIBRATION MODEL FOR MOTORBIKE EXCITED BY RIDE TEST

This research proposes a multi-input multi-output model (MIMO) to identify the modal properties of a motorbike during the riding test. The MIMO process verifies that a linear combination of all inputs causes each output, and there are no causal relationships between the inputs. If there are causal relationships between one of the outputs, the MIMO process redefines the input signals. The process verifies the connection between input-output and the presence of noise extraneous to the inputs and outputs. The MIMO process represents a multiple-input system with a single output. The peculiar aspect is the decoupling of individual information. In the presence of coupling between the separate inputs, the authors propose the principal component analysis (PCA) to decouple the inputs.
