| Abstract: | This paper has summerized the basic methods of dynamic analy-sis,such as the principle of the modal analysis and the forced response simulation. By applying the methods, the experimental modal analysis and the calculation of the forced response simulation have been carried out on Model 482Qdiesel enging cylinder block. The weak sections of the cylinder block have beendetermined according to the result of above analysis and the improvement in design has been made which produces a much better dynamic characteristics of thecylinder block. |
