| Abstract: | Test of structural dynamics are widely used in the study on mechanical structure of agricultural machinary, and it plays a very important role in the field. However, it is difficult to perform such a test for structure with large scale or high precision. It may be fulfilled by the means of the scaled model test. In the paper, the theory of scaled model, whose material of structure may be different from the prototype, is discussed based on the basic beam theory and sensitive analysis of structure. And a new method, the model comparison method, is developed to make the test model equivalent to the original structure. The means of the model modification by analyses of structural sensitivity and the modal shape is described. The method has been proved by beam and frame structures composed of beams, and the results are satisfactory. The method may be further developed to analyze structural dynamics in other fields in future. |
