研究陶瓷餐具多次跌落工况下的损伤表征技术，并建立了理论模型。采用跌落试验测试了陶瓷餐具多次跌落破损加速度与跌落次数的关系，基于理想弹塑性模型,建立了其多次跌落工况下的损伤表征技术描述方程。结果表明：多次跌落工况下陶瓷餐具最大耐受加速度与承受激励次数直接关联，其跌落破损特性呈现累积特征，所建立模型能有效描述这一特性。研究结论对指导陶瓷餐具的物流与销售防护、产品强度改进设计等，具有重要价值和指导意义。

The damage characteristics of ceramic tableware under multiple dropping impacts were investigated and the theoretical model was established. The relation between damage acceleration and dropping times of ceramic tableware was studied with multiple dropping tests. The damage characterization formulation was established based on ideal elastic-plastic model. The results showed that the maximal endurance acceleration of ceramic tableware has close relation with dropping times and the damage characterization is of accumulation character; the established model can describe this characteristic effectively. The purpose was to provide reference for protection of ceramic tableware in logistics and selling, and for strength improvement of product.
