中文摘要：
针对国内某厂铝合金汽车板用气垫式连续热处理线,分析主要工艺设备张力工作特点,采用间接、直接两种张力控制模式对传动系统实施速度和转矩控制,建立了典型工艺设备张力控制方法及整线张力平衡控制策略,构建了以工艺数学模型为核心的张力控制系统。实测表明,静态张力控制精度为-0.05%~0.65%,动态张力控制精度为-3.65%~3.75%,满足热处理线对张力控制精度的需求。
英文摘要：
Based on domestic air-cushion continuous heat treatment line for aluminum alloy automobile sheet, tension work characteristics of the main process equipment is analyzed, indirect and direct tension control mode are adopted for dirve system’s velocity and torque control. And tension control method for typical process equipment and whole line tension balance control strategy are established, tension control system which centered on process mathematic model is constructed. The results show that static tension control precision is-0.05%~0.65%, and dynamic tension control percision is-3.65%~3.75%, both of which meet the needs of heat treatment line for tension control percision.
