【摘要】:在靜態(tài)試驗(yàn)及大量數(shù)值計(jì)算的基礎(chǔ)上提出一種中間坯快速剪切擠壓連接機(jī)構(gòu),可以同時(shí)完成上、下剪刀的水平運(yùn)動(dòng)和相對(duì)運(yùn)動(dòng),從而實(shí)現(xiàn)中間坯的快速連接。為了探究該機(jī)構(gòu)的特性,基于ADAMS動(dòng)力學(xué)分析軟件,建立了連接機(jī)構(gòu)的多剛體模型,仿真模擬了機(jī)構(gòu)的運(yùn)動(dòng)過程,求得了連接機(jī)構(gòu)上、下剪刀的運(yùn)動(dòng)軌跡和水平速度變化曲線,利用ADAMS中帶約束的目標(biāo)函數(shù)法進(jìn)行了結(jié)構(gòu)化設(shè)計(jì),優(yōu)化結(jié)果保證了中間坯的連接厚度,改善了連接過程中速度超前、滯后的問題,有助于中間坯連接過程的順利實(shí)現(xiàn),基于ADAMS的分析和優(yōu)化方法為快速剪切擠壓連接設(shè)備的結(jié)構(gòu)設(shè)計(jì)奠定理論基礎(chǔ)。
[Abstract]:On the basis of static test and a large number of numerical calculations, a quick shearing and extrusion connection mechanism for intermediate billets is proposed, which can simultaneously complete the horizontal and relative motions of upper and lower scissors, thus realizing the rapid connection of intermediate billets. In order to explore the characteristics of the mechanism, based on the ADAMS dynamic analysis software, the multi-rigid body model of the connection mechanism is established, and the kinematic process of the mechanism is simulated, and the moving track and horizontal velocity change curve of the scissors on and under the connection mechanism are obtained. The structural design is carried out by using the objective function method with constraints in ADAMS. The optimization results ensure the connection thickness of the intermediate billet, improve the problems of the speed leading and lagging in the connection process, and contribute to the smooth realization of the connection process of the intermediate billet. The analysis and optimization method based on ADAMS lay a theoretical foundation for the structural design of rapid shearing extrusion joint equipment.
