比例技术在液压传动系统中已得到广泛应用,并取得了显著的经济效益。但在气压传动系统中,由于气体可压缩性大,气压传动系统存在非线性严重、固有频率低及不易稳定等缺点,使比例技术在该领域应用进展速度相对缓慢。我们在研究气缸动态性能测试有关课题时,开发了一套气压比例力控制系统,用于模拟被测气缸的力负载。该力控制系统
Proportional technology in the hydraulic transmission system has been widely used, and achieved significant economic benefits. However, due to the large compressibility of gas and the serious non-linearity of the pneumatic drive system, the low natural frequency and the difficulty in stabilizing the pneumatic drive system, the application of proportional technology in this field is relatively slow. When we studied the subject of cylinder dynamic performance testing, we developed a pressure proportional force control system to simulate the force load of the cylinder under test. The force control system
