The effect of joints model to the vibration characteristics of wood

The One piece of the wooden beam has different vibration characteristics compared to the two pieces of wood with a joint. One of the parameters measured is the dynamic stiffness of wood. The method used is a technique in which the vibration excitation test using a hammer with a rubber head. The wood used in this study is Gofasa (vitex cofassus). The Properties of wood was using the data from previous studies. Vibration characteristic of a piece of wood was used for comparison purposes. Two pieces of wood have joined and secured by bolts. Cantilever beam model has used with the knock in a perpendicular direction to the wood fibres. The joints model used to excitation test is the plain scarf, hooked scarf, half lap splice, and tabled splice. All of these models were tested to determine the characteristics of vibration. The results showed the different vibration characteristics for each model. The results are used as a recommendation of the best models in distributing the vibration from the vibration source.
