책소개

To improve the safety and the stability of the support under mines and reduce the
cost, we design a new slipper-type hydraulic support with energy-efficiency and
high reliability. To study its dynamics, we build a reverse kinematics model. We
analyze the motion and the force for each component of the new support with a
simulation in Matlab/Simulink. The results show that it has appropriate structures
with the required four-bar linkages. To compare the performance between the new
slipper-type support and the traditional support, we design their mechanics
models, deduce their mechanics relations and obtain the force curves for each
component of both supports under the same loads. The results prove that the new
slipper-type support has less demand on oil pressure for the hydraulic cylinder
when working at middle and high positions and it has a larger supporting force
and a higher supporting stability which would be more energy-efficient.
