农机机械科研作为促进农业现代化与自动化建设的主要手段,不仅是提高农业生产效率,减少农业生产成本,降低能耗,提升作业安全性的重要措施,还是顺应农业发展实际需求的关键媒介。而且农业机械设计与结构优化是农业机械发挥成效的灵魂所在... 农机机械科研作为促进农业现代化与自动化建设的主要手段,不仅是提高农业生产效率,减少农业生产成本,降低能耗,提升作业安全性的重要措施,还是顺应农业发展实际需求的关键媒介。而且农业机械设计与结构优化是农业机械发挥成效的灵魂所在,与农业机械性能、质量息息相关,因此农业机械设计与结构优化应充分考量农业生产特点与需求。而农业生产环境的独特性直接导致了农机机械设计与结构存在一定的特殊性,本文以农机车轮为研究对象,研究农机机械设计的有限元分析和结构优化,本文首先在弹塑性有限元法的基础上构建车轮疲劳试验模型,随后借助局部应力应变法预测车轮结构的疲劳寿命,最后合理优化设计农机车轮结构轮辐的方案,在很大程度上提升了轮辐的疲劳寿命,希望能够为相关人员提供一定参考。 展开更多

With the development of mechanization popularity in rural area, agricultural machinery product not only needs to meet the production goals, and also requires the simple operation and human-centered. Human-centered design is always, on the basis of the user' s requirement and usage, to think over the issues by regarding operator as the center, and to design the products by emphasizing the ease of use and understandability during design and manufacture. In this study, Stubble-Mulch Rotocultivator for Boat Tractor (SMRBT) is chosen as the design object. The coordination approach of the user, machine and environment is discussed by deeply investigating their relationship, which is an empirical study of the human-centered technology of agricultural machinery. 展开更多
