The work aims to study the relationship between damage rate and critical bruise fragility of apple. The apple dropping test at multiple heights was designed by the self-made pendulum impact testing machine, the damage characteristics of apple in the drop impact process were analyzed, and the critical dropping height was obtained. The acceleration-curves of apple in the dropping process were obtained from drop test conducted at the place above the critical dropping height. In combination with the peak acceleration amplitude obtained from the test samples dropped at different heights, the bruise fragility of test samples was obtained. According to the apple's damage volume at different dropping heights, the bruise fragility of apple under various damage rates was obtained. The relationship between bruise fragility and damage rate obtained from the study provides reference for the improvement of apple's cushion packaging.
