摘　　要：针对一款165.1 cm(65英寸)轮胎硫化机的工艺特点,采用电液伺服直驱泵控液压系统控制其合模加压和保压环节时的加压缸压力。建立交流伺服电机泵控缸压力控制数学模型,输入相应硫化机及其液压系统的参数,模拟得到压力控制的响应曲线。利用该款硫化机的液压站加压缸进行压力控制实验,分析该系统的超调量、稳态误差和响应时间等相关参数。实验结果表明:加压缸压力控制系统具有良好的动态性能、准确性和稳定性,满足硫化机合模加压和保压的工艺需求。According to the process characteristics of a 165.1 cm(65 inches) tire vulcanizing machine, the electro-hydraulic servo direct drive pump controlled hydraulic system was used to control the pressure in the pressure cylinder in the mold-closing pressure-increasing and pressure keeping links.By establishing a mathematical model of pressure control of the pressure cylinder and inputting parameters of tire vulcanizing machine and its hydraulic system, the response curve of pressure control was simulated. The pressure control experiment was carried out with the hydraulic station pressure cylinder of the vulcanizing machine, and the related parameters such as overshoot, steady-state error and response time of the system were analyzed. The experimental results show that the pressure control system of pressing cylinder has good dynamic performance, accuracy and stability, and can meet the technological requirements of the mold-closing pressure-increased and pressure-kept on tire vulcanizing machine.
