【摘要】:針對起豎機構(gòu)推力大,驅(qū)動缸承載能力要求高的問題,利用ADAMS軟件建立機構(gòu)的虛擬樣機模型,提出了設(shè)置檢測接觸力大小來檢測運動干涉的方法;對鉸支點采用參數(shù)化處理,以最大起豎力為目標(biāo)函數(shù),優(yōu)化了鉸支點的布局,減小了電動缸起豎過程中的最大受力。針對起豎過程中三角臂受力復(fù)雜,應(yīng)力分布不均衡的特點,對三角臂進行了柔性分析,分析了三角臂在初始階段和中間階段的應(yīng)力變化情況,運用拓?fù)浣Y(jié)構(gòu)優(yōu)化方法對三角臂輕量化處理,減輕了機構(gòu)質(zhì)量,節(jié)約了成本。
[Abstract]:In order to solve the problem that the thrust of the vertical mechanism is large and the bearing capacity of the driving cylinder is high, the virtual prototype model of the mechanism is established by using ADAMS software, and the method of setting the detection contact force to detect the motion interference is put forward, and the maximum vertical force is taken as the objective function to optimize the layout of the hinge fulcrum and reduce the maximum force in the vertical process of the electric cylinder. In view of the complex force and uneven stress distribution of the triangular arm in the process of vertical lifting, the flexibility analysis of the triangular arm is carried out, and the stress variation of the triangular arm in the initial and intermediate stages is analyzed. The topological structure optimization method is used to quantify the triangular arm, which reduces the quality of the mechanism and saves the cost.
