摘要

摘要: 为了提高收割机对丘陵山区狭小的梯田地形的适应能力,提高收割机的通过性,将铰接式菱形底盘引入到收割机车架的结构设计中,并对其进行结构优化设计研究。首先针对菱形收割机车架的结构及受力特点,考虑各种典型工况载荷,建立满足各总成布置和实际行驶要求的初始车架有限元模型,并分析了各种典型工况载荷作用下的车架应力分布。然后通过有限元分析结果指导车架的结构尺寸优化,从而实现了菱形收割机车架轻量化设计,缩减了生产成本和设计周期。

Abstract: In order to improve the adaptability of the harvester on the small terraces,the articulated diamondshaped frame is introduced to design of the harvester,and the structural optimization design of the harvester is also implemented. First,the initial finite element model of frame structure to meet the assembly layout and the actual driving requirements is established,based on the structure of the rhombus harvester frame and the mechanical characteristics,and the stress distributions are calculated in a variety of typical operating conditions. Based on the results of analyses,the sectional dimensions of the frame component is optimized,and the lightweight designs of articulated rhombus frame is realized. This design method is capable of reducing the design cycle,and the cost.
