Comprehensive Testing Technology of Mechanical Internal Locking Hydraulic Cylinder

机械内锁紧式液压缸在航天各类产品中应用广泛,其主要用来完成车辆设备的升车运动,使产品精确可靠定位,是实现车辆设备快速调平以及保持车辆平稳稳定的主要元件。目前机械内锁紧式液压缸在最终环节综合测试试验依然采用传统的人工操作为主的试验方法,试验过程中需要多人协同工作,试验控制、参数测量全部由人工操作,操作过程繁琐、效率低下,占用大量的人力、设备。机械内锁紧式液压缸用改进后的自动化试验系统进行自动控制综合测试,依次完成所有试验项目,试验结果均满足设计要求,且数据准确性更高,试验结果数据及过程数据具有可追溯性。

Mechanical internal locking hydraulic cylinder is widely used in various types of aerospace products.It is mainly used to complete the lifting movement of vehicle equipment,so that the product is accurate and reliable positioning,and it is the main component to achieve the rapid leveling of vehicle equipment and maintain the stability of the vehicle during the launch process.At present,the mechanical internal locking hydraulic cylinder still adopts the traditional manual operation test method in the final comprehensive test and test.In the test process,many people need to work together,and the test control and parameter measurement are all operated manually.The operation process is tedious and inefficient,which takes up a lot of manpower and equipment.Therefore,it is of great significance to analyze and study the test method of mechanical internal locking hydraulic cylinder and the causes of abnormal conditions and improve the efficiency and reliability of comprehensive test.The improved automatic test system for mechanical internal locking hydraulic system is used for automatic control comprehensive test.All test items are completed successively and submitted for inspection and acceptance.The test results meet the design requirements and are more accurate.
