摘　　要：传统卷板机工作辊转速不可调节,采用电液变频调速技术以实现上工作辊的无级调速,扩大了调速范围。在对泵控液压马达构成的电液无级调速系统进行静态特性、动态特性等理论分析的基础上,建立了调速系统的数学模型,为工作辊速度调节提供了理论依据,对卷板机方案设计和技术改造具有参考意义。To solve the problem of non-speed adjusting for the three rollers of bending machine,a new electro-hydraulic stepless-speed system of pump-controlled motor is analyzed.On the base of analysis,a mathematical model is established and can be turned into theorical analysis basis.
