Structural Connection Parameter Measurement for Precision Motion Systems Using Accelerometers: A Preliminary Study
Abstract
Accurate modelling is important for both the performance control and monitoring of high-precision motion systems in advanced manufacturing machines. It is not difficult to build dynamic models for motion systems based on the multi-rigid-body system assumption. However, it is usually not feasible to acquire the real connection parameters between rigid bodies like stiffness and damping coefficients especially after mechanical assembly which can be significantly different from their designed values. In this paper, a measurement scheme using multiple accelerometers is presented with discussion of the data processing methods. Simulation results on a three-rigid-body motion system and experimental results on a two-mass motion system preliminarily verify the scheme. Finally, existing problems are put forward for further study.
