摘　　要：该文从工程需要出发,论述了集机、电、液控制为一体的液压同步连续滑移技术,重点探讨连续滑移速度平稳性问题,分析了超速抢载、低速接载、等速接载等3种负载转移阶段平稳性控制策略。经建模分析得出等速接载为首选策略,并通过试验验证了其有效性和可操作性,为类似工程应用提供了理论依据。Hydraulic synchronizing continuous slippage technique which integrates mechanical, electrical and hydraulic control is introduced in this paper on the basis of the practical requirement of some construction projects, and the core of the technique that the smoothness and stability of the speed control is illustrated in detail. Three speed control strategies: excessive speed to turn over the load, lower speed to turn over the load, same speed to turn over the load is presented to accomplish the smoothness and stability in the process of slippage. A optimization of the speed control strategy that same speed turns over the load is educed from the modeling analysis and its validity and maneuverability are tested by practical application, which provides evidence for similar engineering in theory and practice.
