Study on Effects of Circumferential Arc Length on Distribution of Temperature on Pad

  • 摘要: 提出了热流分配系数受摩擦副周向接触弧长影响的观点;使用分段二次插值法确定了摩擦副周向接触弧长和热流分配系数随径向位置的变化关系;基于能量守恒法,计算和比较了2种不同热载荷下闸片的温度及其分布规律。结果表明:周向接触弧长随径向位置呈先增大后减小的变化规律,而热流分配系数的变化趋势正好与其相反;由2种不同热载荷计算得到的温度峰值发生时刻虽接近,但差值较大;温度在径向和轴向方向上的分布规律也不相同。因此,在摩擦副的热分析过程中必须考虑闸片结构带来的影响。
