| Abstract: | The characteristics of straw bowl were discussed,a FEM of the bowl was built. Simulated research on the static compression behavior of straw bowl was performed by FEM,the stress maps of straw bowl along the direction of bowl height distribution were obtained,and its stress distribution properties were analyzed,improvement and optimization design reference was provided.The experimental results were compared with the simulation results,which shows the FEM simulation can obtain the correct results. |
