基于虚拟仪器技术的汽车离合器从动盘检测平台设计

为了提高检测平台的控制性能,设计了基于卡尔曼滤波的复合滑模控制算法,并将其应用于设计的电控系统.同时,为了提高检测平台的自动化程度和可靠性,基于NI公司虚拟仪器技术开发了检测平台的用户界面程序和数据采集控制程序,并利用软件的强大功能,简化了外围设备.经仿真及实际检测验证,开发的检测平台测试精度和检测效率得到了较大提高,位移和力矩检测精度分别达到了±0.005 mm和±0.05 N·m,并且运行稳定可靠.

Design of detection platform for automobile clutch disc based on virtual instruments

To impr ove the co nt rol performance of the detect io n plat form, a compo und sliding mo de contr ol algo rithm w as proposed o n the basis o f the Kalman filter and w as applied to the designed elect rical contr ol sy stem. T o make the detect ion plat form simple and reliable, the interface and data acquisit ion pro grams w er e developed based on the virtual inst ruments technolo gy N1 company . By the pow erful functio n so ftw ar e, the number of the peripheral equipment w as reduced. The simulat ion and measurement result s show that the detect ion precision o f displacemet and torque fo r the detect ion plat fo rm are ±0. 005 mm and ± 0. 05 N·m, that the accuracy and ef f iciency hav e been impr oved and that the detect ion plat form stable and cr edible.
