Optimal Design of Rubber Mounts Supporting Notebook HDD for Shock and Vibration Isolation

Notebook PCs, especially its hard disk, suffer impact-induced failure as well as vibration problems. Consequently shock and vibration performance plays a decisive role in the product design. To minimize the likelihood of failure in such cases, cushioning materials are often used. In this paper, we analyzed dynamic characteristics and shock response of the system supported by non-linear rubber mounts using modal parameters extracted from vibration test. In addition, optimal design of rubber mount was developed.
