- Abstract:
- The dynamics analysis software ANSYS/LS-DYNA is applied to establish the FSl( fuid and solidinteraction ) model of unloading cartridge valve in a huge metal extruding machine in this paper, Through stud-ying algorithm and control state equation of the fuid-solid coupling unit and the simulation analysis of fuid.solid coupling, this paper studied the transient mechanical characteristics of cartridge valve and the impactcharacteristics under the interaction of the valve core in unloading process. The results show that: the stabilityof unloading process is related to the contacting time between valve core and valve set, the oil squeezing timehad better not exceed 0. 01 second, the peak impact force of oil to valve core is 140 KN in a steady unloadingprocess, and the maximum Von Mises stress between valve core and valve set is 456 Mpa.
