摘　　要：以玉露桃为试验对象,进行了不同下落高度、不同桃质量和坚实度等对碰撞参数(如力峰值、到达力峰值时间、碰撞总时间、力峰值/到达力峰值时间的比值等)影响的碰撞特性试验。结果表明,3个试验因子对力峰值/到达力峰值时间的比值、损伤体积和力峰值的影响大多为显著。碰撞参数之间存在较大相关性。碰撞损伤预测模型可采用V=-8.77+0.161h+1.24m+0.031f来表达。Impact trial of peach using cultivars ‘Yulu＇ was undertaken to determine the effects of different dropping heights, fruit mass, and fruit firmness on impact characteristics of peach fruits. The results showed that the effects of the three experimental factors on the impact parameters （contact time, time to peak force, peak force, and peak force/time to peak force） were significant. There was a great relation between the impact parameters. The impact variation bruise was predicted by the modal V = - 8.77 ＋ 0. 161h ＋ 1.24m ＋ 0.031f.
