【摘要】 对挖掘装碴机工作机构的工作原理进行了分析,对组成结构进行了设计;根据土壤切削理论和连杆机构运动及动力分析方法,对挖掘装载机工作机构的各组成部分的最大挖掘阻力进行了计算,利用有限元法建立了工作机构的整体计算模型,对各构件进行了强度和刚度计算。结果表明工作机构设计是合理的,油缸选型和工作压力值设定是正确的。更多还原

【Abstract】 The working machanism principle and structure are designed and analysed.The maximum resistance of each machanism is calculated according to soil cutting theory and machanism analysis.The finite element analysis model is constructed,stress and strain of working machanism are calculated precisely.It is confirmed that the machanism structure meet the requirement and the type and parameter of hydraulic cylinder are proper.更多还原
