摘要	采用类似液体装甲的轮子进行高剪切和低压研磨具有显著优势，例如加工质量良好、适应性强以及成本低。它在精密加工领域具有相当大的应用潜力。提出了一种理论分析模型，以理解类似液体装甲轮子的高剪切和低压研磨中的散热机制以及热源的分布情况。首先，通过结合流体动力学和传热学，求解了工件表面与轮子界面处切削膜的对流换热系数。然后，建立了高剪切和低压研磨的热源模型。解决了热源分布为三种不同形状（即矩形、三角形和梯形）时的温度场。此外，分析了磨削速度、工件进给率和法向磨削力对热源分布形状的影响。最后，在实验平台上使用热电偶测量了磨削过程中的磨削温度，以验证该模型。研究结果表明，与矩形和三角形热源分布相比，梯形热源分布的误差最小。理论分析结果和有限元模拟结果与测量的温度值高度吻合。分析结果的平均误差为 5.5%。理论温度随着磨削速度和垂直磨削力的增加而升高，而随着工件进给率的增加而降低。在本研究中，当磨削速度为 14 米/秒时，测量到的最高温度仅为 91.68°C。该温度明显低于传统磨削的温度。本研究为高剪切和低压力磨削过程中的热行为和热产生机制提供了理论指导。
Abstract	High-shear and low-pressure grinding with the liquid-body-armor-like wheel has significant advantages, such asgood machining quality, high adaptability, and low cost, It has a considerable potential for application in thefield of precision machining. A theoretical analytical model was proposed to understand the heat dissipationmechanism and the distribution of the heat source in the high-shear and low-pressure grinding with liquid-bodyarmor-like wheel. Firstly, the convective heat transfer coeffcient of the cutting film at the interface of theworkpiece surface and wheel was solved through combining the fluid dynamic and the heat transfer. "Then, a heasource model for the high-shear and low-pressure grinding was established. The temperature field under threedifferent shapes (i.e, rectangular, triangular, and trapezoidal) of the heat source distribution were solvedAdditionally, the effects of grinding velocity, workpiece feed rate, and normal grinding force on the shape of theheat source distribution were analyzed. Finally, the grinding temperature during the grinding process wasmeasured using the thermocouple on the experimental platform to verify the model. The findings show thetrapezoidal distribution of heat sources has the minimum error as compared with the rectangular and triangulalheat source distribution. The theoretical analytical results and finite element simulation results agreed well withthe measured temperature values. The average error of the analytical results was 5.5 %. The theoretical temperature increased with the grinding velocity and the normal grinding force, t decreased with the increase in theworkpiece feed rate. 'The highest measured temperature was only 91.68 'C at the grinding velocity of 14 m/s inthis work, The temperature was significantly lower than that of the conventional grinding. This study providestheoretical guidance for the thermal behaviors and heat generation mechanisms in high-shear and low-pressuregrinding processes.
