摘　　要：在分析新型多位气缸运动过程的基础上 ,应用热力学和空气动力学的基本理论 ,对新型多位气缸的每一个行程都建立了动态特性数学模型 ,采用四阶龙格 -库塔法对各腔压力变化、活塞位移和运动速度进行了数字仿真。这对了解该新型多位气缸的性能和实际应用提供了重要依据。Basing on the analysis of the moving process of the new type of multi-position pneumatic cylinder,applying the basic theories of thermodynamics and aerodynamics,the mathematical model of dynamic characteristics of the new type of multi-position pneumatic cylinder were set up.The pressure in the pneumatic chamber,the displacements and the speeds of the piston were simulated by four-step Rounge-Kutta.It provides important parameters for making use of this pneumatic cylinder.
