The raw data of analysis of simple harmonic experiment of fiber curve laying laminates
Description
The greater the damping ratio of the composite laminates, the better the vibration damping performance. Fiber curve laying laminates are made in the method of [0/45/<0|15>/-45]s,[0/45/<15|30>/-45]s,[0/45/<30|45>/-45]s, [0/45/<45|60>/-45]s , [0/45/<60|75>/-45]s ,[0/45/<75|90>/-45]s. After simple harmonic vibration analysis of the laminate, the response of the acceleration under the simple harmonic excitation force can be obtained.The raw data of analysis of simple harmonic experiment can be gotten from acceleration sensor and transmitted to the dynamic analyzer. Applying a simple harmonic force to the composite laminate through a simple harmonic exciter, the magnitude of the force is f ( x ) = sin(10Πt ). Explanation: The txt files with the naming form of 0_15, 15_30, 30_45, 45_60, 60_75, 75_90 are the data from test instrument. The name of each file represents placement method of each fiber curve laying laminate. For example,0_15 means [0/45/<0|15>/-45]s, 15_30 means [0/45/<15|30>/-45]s ,etc.
