In the endurance test of integrated electro-hydraulic brake system,different caliper loads need to be replaced for products with different fluid discharges.To address this problem,a simulated caliper load with adjustable cylinder volume to adapt to different fluid demands was designed.A simulation model was built based on the simulation software AMESim to analyze its flu-id demand-hydraulic characteristics,and then a set of integrated electro-hydraulic brake system endurance test system was devel-oped based on CAN communication.The endurance test of conventional braking power,ABS and other functions of the tested product was carried out.The load mechanism can be selected from the simulated caliper device or the real car caliper through the ball valve.The experimental results show that the simulated caliper load can meet the endurance test of the product under test,and the difference between the load and the caliper is very small,which meets the testing requirements of the manufacturer.
