笔记本电脑脚垫参数优化设计

Optimal Design for Parameters of Buffer Foots on Laptop

针对不同橡胶制成的笔记本电脑缓冲脚垫进行单轴试验,获取各种橡胶的强度参数。建立笔记本简易有限元模型,研究橡胶材料缓冲脚垫在不同形状、大小、厚度及位置分布的情况下,笔记本电脑在正面跌落条件下对硬盘的加速度响应。建立整机有限元模型,进行整机的跌落试验测试分析,验证简易模型的结论,并得出优化的结果。

The uniaxial compression test of the buffer foots on laptop made by different rubbers was carried out so as to obtain their strength parameters.A simple finite element model for laptop was established to study the acceleration response of hard disk in drop of laptop when the rubbers differed in shape,size,thickness and distribution of locations.And then,a whole finite element model was established to do the drop test analysis,verify the results of the simple model and get the optimal results.
