SV00 - 3 position 4 port hydraulic
servovalve
三位四通液压伺服阀
Description
SV00 is a simple submodel of a 4 ways 3 positions hydraulic
servo-valve.
SV00S是个简单的三位四通液压伺服阀
The spool dynamics is modeled as a 2nd order system with a
specified natural frequency and damping ratio.
线轴动力学建模为二阶系统与一个指定的固有频率和阻尼比
For each of the 4 possible flow paths in the central position :
在中位的四个可能的流量路径：
P to A, P to B, T to A and T to B
a flow rate in L/min and a corresponding pressure drop in bar must be
specified for the path fully open. Also the critical flow number for
transition between laminar and turbulent flow characteristics must be
given for each flow path. Normally this dimensionless number can be
left at the default value.
流量（L/min）和对应的压降（bar）必须是在阀口全开的情况下。层
流和湍流流动特性临界流数之间的过渡必须给每个流路径。通常这个
无量纲数可以留下作为默认值。
A deadband region can be specified. In this deadband it is assumed
that for each flow path there is no flow.
可以指定一个死区。在这死区假设对于每个流量路径没有流量。
For the two other positions, the flow paths are :
•
•
from P to A and from B to T in the left block
from P to B and from A to T in the right block
