    摘要:

    進(jìn)給伺服系統(tǒng)的性能對數(shù)控機(jī)床的跟蹤及定位精度、加工質(zhì)量等有著重要的作用。摩擦和間隙的非線性會導(dǎo)致系統(tǒng)的爬行、振蕩等不穩(wěn)定行為。針對閉環(huán)控制的直聯(lián)式進(jìn)給伺服系統(tǒng)，建立了考慮摩擦和間隙的綜合力學(xué)模型和數(shù)學(xué)模型。研究了低速進(jìn)給條件下摩擦和間隙非線性對工作臺輸出的影響，得出了工作臺產(chǎn)生爬行現(xiàn)象的幾種可能條件，并給出消除進(jìn)給系統(tǒng)爬行現(xiàn)象的幾種常見措施。所得結(jié)論為進(jìn)給伺服系統(tǒng)的優(yōu)化設(shè)計(jì)和性能預(yù)測提供了理論支持。

    Abstract:

    The performance of the feed servo system has an important effect on CNC machine tools, including the tracking and position accuracy as well as the surface quality of the machined part. The nonlinear factors such as friction and backlash can induce unstable behaviors such as stick-slip and oscillation of the feed servo system. The mechanical and mathematical models containing friction and backlash were established for the motor direct-connected feed servo system with close loop controller. The effects of friction and backlash on the worktable under low feeding velocity were studied. A few of possible conditions for the stick-slip occurrence of the worktable were obtained. And some means for cancelling the stick-slip behavior of the feed servo system were presented at last. The research results provided a theoretical support for the optimum design and performance forecast of the feed servo system.
