The Analysis of Vibration Resistance of the Shape and Braided Laminated Manufactured Structure Using Taguchi Method

Abstract

In this study, the L934 orthogonal table of the Taguchi method is used as a systematic parameter analysis. A rapid prototyping machine (RPM, manufactured by the research team) and fused deposition modeling (FDM) are used to make anti-vibration test specimens and to analyze the effect of different process parameters, such as weaving and shaping, on vibration resistance. Hopefully, various application fields will be extended via the deposition method. The impact test is executed by dropping a steel ball onto each test piece which is connected to an accelerometer and a PW700 spectrometer for extracting the frequency response during the impact. The vibration performance under different process parameters is analyzed. Several parameters that may affect anti-vibration performance are selected under the existing process, namely weaving method (A), deposition thickness (B), weaving density (C) and cross weaving per n-layer (D). The policy is to evaluate the required time period to restore to the steady state after impact. Hence, the shorter the convergence time is, the better the specimen resists the vibration. The experimental results show that the build-up layer thickness and the weaving density are the main control factors that affect the anti-vibration ability most. The process parameter A3B1C1D2 obtains the best vibration resistance performance.
