摘　　要：分析了平地机功率损失的原因,并借鉴国外平地机功率控制策略,研究如何使发动机工作在全负荷状态。分析结果表明:滑转率和液力传动效率影响着机器的功率利用率,严格控制这两个因素,对改善整机性能至关重要。We have analyzed why power lost to the grader while viewing how power is controlled in graders overseas so as to carry out a study on how to put the grader's engine operating at full load conditions. Analytic results show that slippage rate and hydraulic trans efficiency do affect power availability of the whole machine; therefore, strictly controlling these 2 factors is critical to improve performance of the grader as a whole.

关 键 词：功率控制 平地机 发动机 滑转率 液力传动效率
