为了解决增压缸增力适应问题,研究了增压缸内置二位三通阀动态特性. 利用AMEsim软件中气动及液压零件库组件对该二位三通气控阀进行了建模与仿真,分析了该阀处于不同工作压力下位移、速度、质量流量和焓流量曲线. 结果表明:在工作压力为0.5 MPa时,该阀的换向时间约为195 ms;当工作压力为0.5~0.8 MPa范围内,气源压力每增加0.1 MPa,该阀换向速度加快约为13 ms;质量流量与焓流量峰值随着气源压力增大而增大,但其达到峰值时间与趋于0点时间基本没有变化. 该二位三通阀的启动压力约为0.24 MPa,响应时间约为35 ms. 数学计算与软件仿真数据误差在可接受范围,结果可靠.

To solve the problem of pressure cylinder power adaptation, the dynamic characteristics of built-in two-position three-way pneumatic control valve in the pressure cylinder was studied. The built-in pneumatic control valve was modeled and simulated by using the pneumatic component design and the hydraulic component design components library of AMEsim software, and the displacement, velocity, mass flow and enthalpy flow of the valve under different working pressures were also analyzed. The results show that the reversing time of valve is about 195 ms when the working pressure is 5 bar, and the valve reversing speed increases 13 ms when the working pressure increases 1bar every time in ranges of 0.5-0.8 MPa; the peak values of mass flow and enthalpy flow of built-in pneumatic control valve increase with air pressure increasing, while the time to peak values and to 0 values have no significant differences. What’s more, the start-up pressure of built-in pneumatic control valve is 0.24 MPa, and the response time is about 35 ms . The mathematical results and simulation data remain in an acceptable range, and the results are reliable.
