摘　　要：导轨部件通常是整个机床刚度链中的最薄弱环节之一,因此导轨的力学性能直接影响机床整机的动态性能。提出了一种基于铁基多孔含油材料结合面的滑块型滑动导轨,分析了多孔含油材料结合面的刚度和阻尼特性;设计了多孔含油材料滑块型滑动导轨的一种矩形截面导轨形式,并对其润滑与低速平稳性进行了分析和实验验证;分析了所设计滑动导轨的导向精度,提出了滑块型滑动导轨设计时滑块跨度的设计原则。同滚动导轨相比,结果表明:该类型导轨具有高刚度、大阻尼和自润滑的特点,适合应用在中、较重负荷精密机床。Guide way is usually one of the weakest parts in the whole stiffness chain of machine tools. Therefore,the mechanical properties of it can affect the dynamic performance of machine tools. A novel slier-sliding guide way based on Fe-based oily porous material joint interface was presented. The stiffness and damping properties of the oil porous material was analyzed,the lubricating and low-speed stability were analyzed and experimental verified. Meanwhile,the guiding precision of designed guide way was simulated,and a design principle of the slider span was proposed. Comparing with the rolling guide,the result shows that the designed guide way with high stiffness,high damping and self-lubricating characteristics,is suitable for the heavier load precision machine tools.
