【摘要】:針對(duì)起豎機(jī)構(gòu)推力大,驅(qū)動(dòng)缸承載能力要求高的問(wèn)題,利用ADAMS軟件建立機(jī)構(gòu)的虛擬樣機(jī)模型,提出了設(shè)置檢測(cè)接觸力大小來(lái)檢測(cè)運(yùn)動(dòng)干涉的方法;對(duì)鉸支點(diǎn)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(diǎn)的布局,減小了電動(dòng)缸起豎過(guò)程中的最大受力。針對(duì)起豎過(guò)程中三角臂受力復(fù)雜,應(yīng)力分布不均衡的特點(diǎn),對(duì)三角臂進(jìn)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(yùn)用拓?fù)浣Y(jié)構(gòu)優(yōu)化方法對(duì)三角臂輕量化處理,減輕了機(jī)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.
