一种用于结构静力试验的电液伺服控制加载系统

Electro-hydraulic Servo Control Loading System for Static Test

结构静力试验是研究复杂工程构件静特性的重要手段,是校核产品设计静强度、刚度、稳定性,鉴定产品可靠性的有效途径,并为产品结构设计和产品结构优化提供可靠的静强度数据和最准确的资料。电液伺服控制加载系统是土木工程结构试验中理想而不可缺少的试验加载设备。基于LabVIEW研制与开发的伺服控制加载系统省略传统的信号发生器等硬件设备,其精度更高,性能更稳定,操作简单且能根据试验要求做进一步扩展和优化。

Static test is an important means of researching on static characteristics of complex engineering structures and an effective way of checking product design strength,stiffness,stability,identification of product reliability.The reliable static strength data and accurate information can be provided for the design of product structure and the product structure optimization in this test.The electro-hydraulic servo control loading system is the ideal and indispensable test loading equipment in the civil engineering structures test.The traditional signal generator hardware is omitted in the servo control loading system based on LabVIEW.The system is characteristic of more accurate and more stable performance and simple operation and can be further extended and optimized according to test requirements.
