    摘要:

    分別采用偽剛體模型和擬柔性模型對(duì)雙自由度全柔性五桿機(jī)構(gòu)進(jìn)行了分析，建立了不完全分布柔度全柔性五桿機(jī)構(gòu)的偽剛體模型和擬柔性模型，推導(dǎo)出外載荷與位移關(guān)系的一般公式。設(shè)計(jì)了一微型對(duì)稱(chēng)全柔性五桿機(jī)構(gòu)，利用剛性五桿機(jī)構(gòu)幾何關(guān)系和迭代程序，給出了該機(jī)構(gòu)擬柔性模型的理論計(jì)算結(jié)果，同時(shí)用ANSYS對(duì)該實(shí)例進(jìn)行了分析。通過(guò)實(shí)例的理論計(jì)算和有限元分析結(jié)果的比較，驗(yàn)證了理論推導(dǎo)的正確性，同時(shí)也驗(yàn)證了擬柔性模型分析方法的有效性。

    Abstract:

    A fully compliant five-link mechanism of two-DOF was analyzed with both pseudo-rigid-body and imitate-compliant-body models. The pseudo-rigid-body and the imitate-compliant-body model of the fully compliant five-link mechanism were also established and the equation of relationship for load and displacement was presented. A symmetry fully compliant five-link micro-mechanism was designed. By using the geometric relationships of the rigid five-link mechanism and the iterative program, the results of deformation analysis in imitate-compliant-body model method for this micro-mechanism were given. At the same time, the simulation analysis in the FEM method for the micro-mechanism was also given. Compared the results with computer and FEA, the validity of the imitate-compliant-body model was proved to be effective.
