| 摘 要： | 针对现有轴承实验台的加载力不可按照任意载荷谱调节的缺陷,提出了PLC与虚拟仪器共同控制的方案.下位机采用PLC进行简单可靠控制,上位机采用虚拟仪器进行复杂的加载控制.详细阐述了控制方案及与PLC传输协议协调的实现方法.在允许的载荷输入范围内,该方案通过实验台加载力的可调输入,进行设定载荷谱试验,使试验时间有效缩短.试验结果表明,该方案灵活,且成本低,满足了产品测试需求.

| Abstract: | To overcome the defects of the existing bearing test bed that the loading force cannot not be adjusted in accordance with arbitrary load spectrum,the control scheme combining PLC and virtual instrument is proposed.Simple and reliable control is conducted by PLC in lower level,and by adopting virtual instrument in upper level for complex loading control.The control scheme and coordinated implementation of PLC transmission protocol are described in detail.Under permissive load range,this scheme is conducting ... |
