As a necessary device of measuring hydraulic parts, the hydraulic test-bed is able to measuring vary of parts such as pumps, motors and valve. The hydraulic motor is heart of whole hydraulic system as a part of power and executing, it results in the dependability of hydraulic system; even in the good working condition of the manufacturing equipments.Therefore, measuring accurately to the hydraulic motors is the way of promotion of construction, process and performance of products. The designing is depending on these standards:1.The Standards of Hydraulic Cylinder(Motors) Test Procedure(GB/T 15622-1995[1]);2.The rules of Hydraulic Cylinder Test Procedure(JB/ZQ3774-86);3.The standards of SAEJ2214 MAR86.The designing is the combination of modern technology of sensors, micro-computers and Computer-aided Test (CAT) which conforms to the standards of ISO and GB.
