Research on elastic modulus of wooden crates for simulation

On the basis of the software of Solid Edge, the 3D solid model design and the manufacturing process sheet of the wooden crate were obtained. According to this process sheet, the sample crate was manufactured to do the stacking test. During the test, experimental data were recorded and processed. Applying inverse method combined with finite element method, the CAE model was quickly reconstructed on the basis of 3D solid model. By finite element analysis, deflections of the model were computed. By comparing deflections to experimental data, elastic modulus of the model can be adjusted to meet the requirements. The research on elastic modulus will establish the foundation for determining CAE model and optimization of structural design of wooden crates.
