Abstract: The loading speed of the connecting rod fracture splitting(FS) machine is one of the important factor affecting the FS quality. In order to investigate the FS machine loading speed characteristics to realize the optimization of loading speed, the virtual prototype simulations were performed. A mechanical and hydraulic model was built for the FS machine using ADAMS/View and ADAMS/Hydraulics modules. The control system models were built for the constant input control system and the input control system with displacement feedback signal. The simulation parameters were set, and the dynamic simulations were accomplished. The loading speed characteristics were analyzed based on the simulation results. In the constant input simulations, it was found that the FS cylinder loading speed 118 mm/s was good for FS quality control as well as for the hydraulic system design. In the displacement feedback input simulations, it revealed that the elliptic input control curve made the most obvious deceleration during the latter half of FS cylinder stroke. The actual loading speed of FS cylinder can be controlled according to the above mentioned curve.

Key words: materials systhesis and processing technology, connecting rod fracture splitting(FS), loading speed of FS machine, combined simulation, ADAMS, Simulink
