液压缸可靠性新型综合试验装置的研制

Development of a New Test Bench for Reliability Research of Hydraulic Cylinder

为了促进液压缸可靠性特别是可靠性综合试验方法、试验装置的研究,研制一种具有功率回收功能的液压缸可靠性新型综合试验装置。该试验装置不仅能对液压缸进行常规的型式试验或出厂试验,还能在额定应力水平或加速应力水平下进行可靠性试验,用户可以根据具体产品的载荷谱编制控制加载规律,加载可变应力包括液压缸偏载力、油温、压力和速度。该试验装置具有节能、检测精度高和安全可靠的特点。

In order to promote hydraulic cylinder reliability research,especially its reliability test approach and novel test device research,the development of a new test bench with power recovery for the reliability research of hydraulic cylinder was introduced.With the new test bench,not only normal type test or predelivery test can be conducted,but also reliability test under normal or accelerated stress level can be conducted.In any reliability test,the user can compile and control the loading laws according to the real load spectrum of any cylinder product,the variable loading stresses include side load,oil temperature,pressure and velocity of the cylinder.The developed new test bench has advantages in obvious energy saving,high test precision,safety and reliability.
