| Abstract: | A flexible multibody dynamic experiment is carried out by using a two beam planar mechanism.The constitution of the experimental system is described and the principle to measure elastic vibration displacement of flexible beams under going over all motion by means of strain measurement technique is expatiated.The procedures and results of model analysis experiment and dynamic response experiment are depicted.The accuracy and reliability of experimental results are testified by comparing them with the corresponding simulation results. |
