拖拉机液压提升能力和输出功率试验CAT技术应用

CAT for Tractor Hydraulic Lift Capacity and Power Output

介绍了拖拉机液压提升能力和输出功率试验测控系统的组成原理及CAT(计算机辅助试验)技术在其中的应用.通过上海50拖拉机的实况测试,证明该系统实用、可靠、精度高,并给出了液压输出功率、压力、流量曲线.

Principles of measuring and monitoring system for the test stand of tractor hydraulic lift capacity and output as well as the application of CAT in the system are presented. With actual test of Shanghai-50 tractor the system proves practical,reliable and accurate. Also presented in the paper are the curves of hydraulic output,pressure and flow.
