中文摘要:
      为了全面揭示湿式制动器在持续工况下的温升变化情况,本文以用于矿山机械的湿式多盘制动器作为研究对象,通过仿真分析和台架实验分析持续工况下的摩擦盘的温度变化。并利用正交试验设计和交互作用分析确定影响摩擦盘温升的最显著因素以及各因素之间的交互作用对温升的影响。结果表明:(1)摩擦盘在径向上的温度变化大于在周向上的温度变化。(2)对于无轨胶轮车来说,应避免速度在40km/h附近制动。(3)影响摩擦盘温升的最显著因素为制动速度,其次是制动时间,最小的为制动力。(4)在多因素交互分析中,制动力与制动时间的交互作用最明显,这两个因素的联合作用对摩擦盘温升影响较大。该研究可为湿式制动器的设计、优化提供理论基础,并为如何避免热变形和热失效提供思考角度。
英文摘要:
      In order to reveal the change of wet brake’s temperature rise under continuous working conditions, the wet multi-disc brake used in mining machinery was taken as the research object., and the temperature change of friction disk under different working conditions was analyzed by bench experiment. The temperature change of the friction disk is compared with the simulation results to verify the correctness of the model. Also, orthogonal test design and interaction analysis were used to determine the most significant factors affecting the temperature rise of the friction disk and the effect that interaction between the various factors has taken on the temperature rise was analyzed. The results show that: (1) the temperature change of the friction disk in the radial direction is greater than that in the circumferential direction (2) For trackless rubber tires, the braking speed should be avoided around 40km/h. (3) The most significant factor affecting the temperature rise of the friction disc is the braking speed, followed by the braking time, and the braking forc. (4) In the multi-factor interaction analysis, the interaction between braking force and braking time is the most obvious. This research can provide a theoretical basis for the design and optimization of wet brakes, and provide a perspective for how to avoid thermal deformation and thermal failure.
