摘要
针对目前我国果园深松机深松铲的铲柄与机架联接处经常由于强度不够而出现变形、断裂和损坏等现象,设计了一种凿型铲式深松机。采用CATIA对凿型铲式深松机三维建模,运用ABAQUS、ISIGHT与FE-SAFE软件对凿型铲式深松机数字化模型进行结构优化设计与疲劳寿命分析。田间试验结果表明,轻量化后的深松机作业时,当前进速度为2.1 km/h、耕深为350 mm、土壤含水率为15%时,强度性能扭矩最小,深松效果最佳。通过软件ISIGHT的优化设计及FE-SAFE的疲劳寿命分析后,整机质量由0.55 t降低到0.45 t,降低了16.4%,实现了轻量化设计,为果园深松机的自主研发提供一定的参考。
In view of the phenomenon of deformation,fracture and damage at the joint of shovel handle and frame of orchard subsoiler in China,a chisel-type shovel subsoiler was designed.CATIA was used to build the 3D model of the chisel-type shovel subsoiler.ABAQUS,ISIGHT and FE-SAFE software were used to optimize the structure and analyze the fatigue life of the digital model.Field test results showed that when the lightweight subsoiler was operating,the forward speed was 2.1 km/h,the tillage depth was 350 mm,and the soil moisture content was 15%,the smaller the strength performance torque was,the best subsoil effect can be got.After the optimization design of the software ISIGHT and the fatigue life analysis of FE-SAFE,the mass of the whole machine was reduced from 0.55 t to 0.45 t,and the mass of the whole machine was reduced by 16.4%,realizing a lightweight design,the research result can provide a certain reference for the independent research and development of orchard subsoilers.
