摘　　要：在分析三级制动位制动能高的计算原则后，给出各级制动位制动能高的计算公式。指出易行车在Ⅱ部位的出口速度和在Ⅲ部位的入口速度应按易行车溜经最后分路道岔的合理速度推算。考虑经济、安全、高效及车辆溜放控制误差，通过分析计算得出易行车溜经最后分路道岔的速度应按４．８５ｍ／ｓ为减速器控制目标，并依此推算Ⅱ、Ⅲ部位的制动能力。his paper analyzes the regulation of determinating the braking capacity in the retarder-dowty hump design, works out the formulas for calculating the three position retarders' braking capacity. The easy-rolling wagon's speeds out of the second retarder and into the third retarder should be calculated according to the wagon's reasonable average speed passing through the last turnout. After analyzing and calculating this speed, considering the economy and efficiancy as well as the braking control error, the speed is decided as 4. 85 m/s as the target speed for the second retarder's control. The braking capacity is calculated according to the speeds out of the second retarder and into the third retarder.
