摘要:
应用动力学分析软件ANSYS/LS-DYNA建立了大型金属挤压机卸荷插装阀FSI模型,从理论上研究了流固耦合单元算法及控制状态方程,并通过流固耦合仿真分析,得出了插装阀瞬态力学特性及卸荷过程中流体与插装阀阀芯相互作用下的冲击特性.研究结果表明:卸荷过程的平稳与闻芯阀套端盖接触时间有关,油液挤压时间最好不要超过0.04s,平稳的卸荷过程中油液对阀芯的冲击力峰值为140kN,阀套最大Von Mises应力为456 MPa.
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 sludying algorithm and control state equation of the fluid-solid coupling unit and the simulation analysis of fuidsolid 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.
