Design and fabrication of simple hydraulic testing machine for bonding strength

Based on bonding technologic features and experimental requirements,a simple hydraulic testing machine for bonding strength was designed and fabricated.The machine can be operated easily due to its simple structure.The design of main structure consists of two frames-the upper and lower frames which form machine frame and transfer components.Mature technology and inexpensive parts such as hydraulic brake pump and hydraulic clutch pump were chosen as hydraulic system and working part.So the cost and the difficulty of fabrication were reduced.The pieces are designed according to typical failure mode.The failure forces were acquired through calculating the pressure of system.The result of experiments shows that the technical index of testing machine can fulfill the requirements.
