Abstract Concerning the development of portable optical disk products, higher impact resistant of the optical pick-up is required. Conventionally, cut and try measures, mainly based on experiment were applied to these problems, and it took much time and cost. Therefore, we developed this drop impact analysis of the optical pick-up based on the Finite Element Method (FEM) and clarified the failure mechanism of the suspension wire breaking with drop impact. With this analysis method, we also developed a new optical pick-up with a curved suspension wire, and realized much higher impact resistance.

Based on the general Biot theory of saturated porous media, a modified time-discontinuous Galerkin finite element method (MDGFEM) is presented to simulate the structural dynamics and wave propagation problems of gas-saturated coal subjected to impact loading. Numerical results of one dimension and two dimensions show that the present MDGFEM possesses better abilities and provides much more accurate solutions than the traditional Newmark method and previous DGFEM for the impact problem. It can effectively capture the discontinuities of the wave and filter out the effects of spurious numerical oscillation induced by high-frequency impulsive load. The results can provide a technological basis for the research of the prevention of coal and gas dynamic disasters under deep mining. And the method could be useful for the further numerical research of coal-rock-gas coupling problems and coal-gas-heat coupling problems subjected to impact loading.
