摘要

摘要为了满足多样化秧苗移栽机构的设计要求，本文基于图论，结合移栽轮系的结构和功能特点，对移栽行星轮系机构的创建方法进行了系统的研究，建立了完整的移栽轮系构型图谱。在行星轮系位移图的基础上，建立了移栽行星轮系的结构和传动比约束。提出了行星轮系齿条、输入、输出部件的选择方法。通过对秧苗移栽机构运动特性的分析，介绍了三种行星轮系的分类，实现了双行星载体轮系(DPGT)结构的系统筛选和分类。共获得适合移植的dpgt 528个，其中5 -bar 3个，6 -bar 13个，7 -bar 92个，8 -bar 420个。解决了单行星载体移植机构不满足多种移植轨迹要求的问题。

Automation creation method for a double planet carrier gear train transplanting mechanism based on functional constraints

Abstract. In order to satisfy the design requirements of diversified seedling transplanting mechanisms, this paper carried out systematic research on the creation method of planetary gear train mechanisms for transplanting based on the graph theory and the structural and functional characteristics of the transplanting gear train so as to establish a complete configuration atlas of a transplanting gear train. The structure and transmission ratio constraints of the planetary gear train for transplanting are established on the basis of the displacement graph of the planetary gear train. Selection methods for the planetary gear train rack, input, and output components are also proposed. The classification of three types of planetary gear trains is introduced by analysing the motion characteristics of the seedling transplanting mechanism, which realizes the systematic screening and classification of the double planet carrier gear train (DPGT) configuration. A total of 528 DPGTs, which are suitable for transplanting, including 3 five-bar, 13 six-bar, 92 seven-bar, and 420 eight-bar DPGTs are obtained. The problem of the single planet carrier transplanting mechanism not satisfying the requirements of a diversified transplanting trajectory is solved.

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
