Topology Optimization of Damping Material Using Dynamic Compliance

Abstract

Less weight is demanded in the automotive development. However, lightweight facilitates the propagation of vibration. Therefore, less damping material must be used in order to solve the problem. For determining the optimal placement of damping material, this research suggest a optimization method using dynamic compliance. Dynamic compliance expresses vibration energy stored in the structure. Especially the imaginary part shows the magnitude of energy dissipation.
