摘　　要：目的:解决球形水果包装量大,发泡网兜包装时不易固定和成型等问题。方法:在以用户需求为驱动的前提下,提出了一种基于AHP/AD/TRIZ相融合的产品设计方法。运用AHP对用户需求进行权重计算并排序,将权重较高的设计元素转化为功能需求;借助AD公理设计完成设计要素的功能域与物理域的映射,得到锥齿轮包装机构、螺旋辅助机构、切刀分离机构和张力控制机构的设计参数集,并构建水果包装机的初始设计矩阵;结合AD独立性公理原则和TRIZ冲突原理的方法进行结构设计;最后运用正交试验进行方案可行性验证。结果:当开膜距离为120 mm、前进速度为65 mm/s、下果管角度为40°时,包装效果最佳,此时的包装成功率为92%。结论:该球形水果自动包装机能解决使用发泡网对球形水果自动包装现有问题,破损率低、效率高。Objective:The paper aims to solve the large amount of packing for spherical fruit packing with unstable and unshapen with foam.Methods:A product design method based on AHP,AD and TRIZ integration was proposed in view of user demands.The weight and ranking of customer demands was obtained through AHP,the high-weights of design elements was converted to functional requirement.Then,the mapping between functional domain and physical domain of design elements was completed by means of AD axiomatic design.The design parameter sets of bevel gear packaging mechanism,spiral auxiliary mechanism,cutter mechanism and tension control mechanism were obtained,and the initial design matrix of fruit packaging machine was constructed.The structural design of fruit packaging machine was obtained by combining AD independent axiom and TRIZ conflict principle.Finally,the feasibility of scheme was verified by orthogonal experiment.The orthogonal test of packaging machine was carried out.Results:The test results showed that when the opening distance was 120 mm,the forward speed was 65 mm/s,and the Angle of the fruit tube is 40°,the packing effect of apple was the best,the success rate of packing machine was 92%.Conclusion:Automatic packaging for spherical fruit could be solved the existing problem of automatic packing by using foaming net,the test index met low damage rate and high efficiency.
