According to the situation of the aging hydraulic loading system for a certain aeroengine test bed,the optimum design for the hydraulic loading system of the test bed was carried out.By means of comparative analysis，the appropriate adjustment method was chosen for the hydraulic pump.A hydraulic loading and control system were developed based on configuration software and VB.NET.By selecting the type of aeroengine from the HMI,the modularization subroutines were called to monitor the data of the system in realtime,and the certain demand of hydraulic loading for different types of aeroengine hydraulic pump was achieved.The test results show that the system has high stability and reliability,and good engineering application value.
