摘要:
针对6000 kN锻压机的3种泄压回路,进行了AMESim建模、参数设置和仿真,对比分析了3种泄压回路中的工作缸的活塞杆位移、速度、加速度特性以及工作缸进出油口的压力脉动和其稳定状态下压力的情况。仿真对比结果表明:泄压开始1 s内,在3种泄压回路活塞杆的位移接近相同情况下,节流阀泄压回路工作缸活塞杆的速度最先达到稳定状态,波动幅度最小,加速度峰值最小,工作缸运动最为平稳,惯性冲击最小;节流阀泄压回路是3种泄压回路中泄压特性最佳的回路,节流-顺序阀泄压回路的泄压特性次之,顺序阀泄压回路的泄压特性最差。
 
For three types of pressure relief circuits of 6000 kN forging press, their models, parameters setting and simulation processes were conducted by AMESim, and the displacement, velocity and acceleration of the working cylinder rod, the port pressure fluctuation on the oil inlet and outlet and the pressure conditions under the stable status were analyzed comparatively. The comparative simulation results show that steady velocity of the working cylinder rod can be reached within 1 s after the pressure relief starts under the condition that displacements of the rod are nearly the same for three types of circuits. At the same time, the fluctuation margin and peak acceleration reach the minimum level, and the most stable motion of the working cylinder can be realized with the minimum inertial impact. The pressure relief circuit of throttling valve is the best in the three types of pressure relief, and the rest sequence is the throttling-sequence valve pressure relief and the sequence valve pressure relief circuit respectively.
