Abstract
The effect of geometric structure on stiffness and damping factor of wood applicable to machine tool structure
Highlights
Wood is a natural material commonly used as building construction
This paper presents the results of stiffness analysis using finite element method (FEM) and experimental testing of vibration damping of wood structure aimed to develop main structure of machine tool
The results show that the elactic modulus as well as vibration damping factor decreased significantly if notch achieved higher than 60%
Summary
Wood is a natural material commonly used as building construction. Various woods have been sold commercially with low cost compared to metal materials. Production process of wood material is easier than metal, so that it reduces the cost production. This paper presents the results of stiffness analysis using FEM and experimental testing of vibration damping of wood structure aimed to develop main structure of machine tool. When a structure is vibrated, its damping capability reduces the amplitude of oscillation and changes the vibration energy into heat. Damping factor is defined as a loss factor or energy loss ratio that was referred to energy transformed into other energy along one cycle vibration (Ouis, 2002)
