A plain plate is often used in structures such as the transportation equipment and home electric appliances. We face challenges of the cost reduction and weight saving in design of product. In this case, it is ideal to achieve them using cheap steel economically. In this study, we focused on the plate given in concavo-convex processing and curved surface processing and it is an object to clarify the difference in vibration characteristics between a plain plate and curved plain plate with rib. We analyzed rib curved plain plate model by means of FEM. We created an experimental model and conducted the experimental modal analysis then we compared the experimental value with the analytical value. In the result, we confirmed the validity of analysis model in out-of-plane vibration. Furthermore we compared the eigenvalue in plain plate and rib curved plate. In the result, we found the eigenvalue rise than the plain plate by using the rib curved plate.
