tension of the need for automatic
adjustment
and the
principle of tension
adjust.A
new kind of tension

iS
designed，the
characteristic of the
device is analyzed and the transfer function is established.On this basis.an overall dynamics
model and mathematic
model for belt
conveyor
are built with this control
system.，nle
automatic control process of belt tension iS
analyzed.In
addition the
caoability
of the tension automatic control
system
is
analyzed using
an
example.The
result of simulation
proves this hydraulic automatic tension system has better adjustment effect and better stability.
