Dynamic Co-Simulation of Fracture Splitting Machine for Connecting Rods
The fracture splitting (FS) method is a bran-new processing technique in the automobile engine connecting rod manufacturing industry, FS is one of three pivotal working procedures, and press speed is one of the key influence factors of FS process. In order to realize parameters of press speed and pull cylinder working pressure, dynamic simulation of hydraulic system has been carried out. Simulation results indicated that press speed of pull cylinder was about 130mm/s, which was between 120mm/s and 150mm/s that was not only good for controlling FS quality, but also not leading irrational design of hydraulic system. The working pressure of pull cylinder was between 10MPa and 14MPa, which was suitable for FS processing. The hydraulic system of FS machine can satisfy the basic requirements of connecting rods FS process. This paper has provided reliable theoretic basis for the design of FS machine for connecting rods.
