卡特彼勒液压缸和阀脉冲试验台，是根据美国卡特彼勒的液压缸和阀脉冲试验台的实际使用经验和技术要求，结合中国大陆的实际情况，而特别定制的脉冲试验台，在试验台的设计上做了一些改进。

试验台是液压、电气一体的测试系统。它旨在完成液压缸和阀的脉冲疲劳试验和阀的泄漏试验，测试液压缸和阀在高压脉冲之下的耐久性。为设备出厂，尤其是新研发的产品，提供了有力的试验数据和性能保障。

 脉冲疲劳试验实际是一种破坏性的试验，它测试设备在一定的高压脉冲之下（42MPa及以下）的耐久性，是以最终实验物件损毁为测试终止条件的。因此对于脉冲试验台本身的硬件和软件的要求尤其为高。

 DYNEX的主泵和换向阀以其长寿命，稳定工作，高换向频率，而特别适合于试验台的项目，在美国卡特彼勒的试验台，以及全球多种设备的试验台上已经取得了广泛的应用。

 上海曼理机电科技有限公司所提供的阀和液压缸试验台已经经过了上千万次的脉冲试验，性能良好。

 Cylinder and valve impulse test stand for Caterpillar R&D Center (China) Co., Ltd., are designed based on US Caterpillar's test stand experience and requirement, facing Chinese mainland real situation, the customized impulse test stands make some design progress on test stand then those in US.

  Test stands integrate hydraulic and electrical control.It dedicated to accomplish cylinder and valve impulse fatigue test and valve leakage test,testing the cylinder and valve long life under high pressure impulse.It supplies believable test data and performance guarantee for components, especially for newly developed products, before them leave factory are very important.

 Impulse fatigue test is a kind of test based on damage,which test a component's long-life(under 42Mpa or lower impulse pressure) till the product broken down.So a test stand itself's hardware and software must be strong enough and have good quality.

  Dynex main pump and direction valve for their long-life and stable working performance, high frequency reversing are very suitable for test stand project,which have been used many years in US Caterpillar test stand and widely used in many kinds of other test stand in the world.  

  Marlin Engineered Technologies(Shanghai) supplies cylinder and valve test stand have worked through tens of millions times of impulse test and still work well.
