Experimental Modal Analysis of the Fiber Reinforced Plastics Pipe and Validation

Pipeline in the actual operation can generate vibration because of the environmental impact,so studying the dynamics of pipeline is necessary.FRP pipe was used for the study.The pipeline vibration modal was analyzed by using finite element.The experiment verifies that both results are generally in agreement with each other.Some suggestions were proposed in the nonlinear structure of the admittance measurements.The method of visual comparison modal type was also put forward.It offers some reference for FRP pipe in its daily operation.
