【摘要】：針對(duì)并聯(lián)機(jī)構(gòu)耦合帶來(lái)運(yùn)動(dòng)學(xué)分析與控制困難的問(wèn)題,提出了一種新型完全各向同性的三維移動(dòng)并聯(lián)機(jī)構(gòu),該并聯(lián)機(jī)構(gòu)動(dòng)平臺(tái)和靜平臺(tái)之間由3條支鏈連接,3條支鏈的第一個(gè)移動(dòng)副在空間中呈正交分布,使得該機(jī)構(gòu)的動(dòng)平臺(tái)具有3個(gè)移動(dòng)自由度,且輸入輸出一一對(duì)應(yīng)。這種機(jī)構(gòu)最突出的優(yōu)點(diǎn)是運(yùn)動(dòng)副簡(jiǎn)單,三維移動(dòng)解耦,運(yùn)動(dòng)學(xué)分析簡(jiǎn)單,便于該機(jī)構(gòu)運(yùn)動(dòng)控制設(shè)計(jì)。采用螺旋理論分析了該機(jī)構(gòu)的自由度及性質(zhì),確定了機(jī)構(gòu)的主動(dòng)副,給出了機(jī)構(gòu)的位置和速度正反解,分析了機(jī)構(gòu)工作空間及運(yùn)動(dòng)性能。根據(jù)機(jī)構(gòu)輸入輸出關(guān)系,求得機(jī)構(gòu)雅可比矩陣,驗(yàn)證了機(jī)構(gòu)具有完全各向同性。研究結(jié)果對(duì)該機(jī)構(gòu)的進(jìn)一步應(yīng)用具有理論指導(dǎo)意義。
[Abstract]:Aiming at the difficulty of kinematics analysis and control due to the coupling of parallel mechanism, a novel fully isotropic 3D mobile parallel mechanism is proposed. The first mobile pair connected by three branches and three branches of the parallel mechanism is orthogonal distributed in space, which makes the moving platform of the mechanism have three moving degrees of freedom. The most outstanding advantages of this mechanism are simple kinematic pair, three-dimensional motion decoupling, simple kinematics analysis and easy motion control design. The degree of freedom and properties of the mechanism are analyzed by using helical theory. The active pair of the mechanism is determined, the forward and inverse solutions of the position and velocity of the mechanism are given, the workspace and motion performance of the mechanism are analyzed, and the Jacobian matrix of the mechanism is obtained according to the relationship between the input and output of the mechanism. It is proved that the mechanism is completely isotropic. The results of the study are of theoretical significance for the further application of the mechanism.
