In order to establish matching contact model, this paper constructed dynamics analysis interface. Setting the valve parameter, inputting valve structure parameters by using MATLAB software platform, can draw the need of valve movement curve.

为了建立匹配性接触模型，论文编制出动力学分析人机界面，该系统对气门落座结构进行了参数化设置，运用MATLAB软件平台将气门结构参数输入，即可绘制出需要的气门运动曲线。

The results show that the new type of proportional direction valve is of good steady state control characteristics and equal displacement characteristics. The linearity of the control curve of the main spool displacement is well. However, there exists a certain neutral position control dead zone.

研究结果表明，新型比例方向阀的稳态特性和等位移特性良好，主阀芯位移控制曲线的线性度也较好，但有一定的中位控制死区。
