Abstract：on the basis of topological evolutionary structural method(ESO) and taking the maximization of loss factor of modality as the target function, and the needed volume of damping material as the constraint condition, the damping element as the design variable, the topological optimization model with damping material of cylindrical shells is build, the topological optimization of constraint damping material and free damping material placement is studied, the sensitivity of damping element location on loss factor of modality is studied, the formula of sensitivity analysis was derived, according to rule of topological evolutionary structural method, gradually deleting the material of low utilization ratio, making loss factor of modality the maximization, the numerical calculation example is presented, which indicates validity and feasibility of the method of topological optimization.
