The LXJ-4-450 large Size Geotecnical Centrifuge, designed and constructed
by our engineers and technicians, was successfully put into operation in
March 1991. Its symmetric rotating arm with the counterweight basket at
one end and a large capacity swing basket at the other, has the characteristics
of excellent dynamic balance and testing accuracy. Operated by a compute
system, the centrifuge is also equipped with a complete safety monitoring,
trouble shooting and alarming system. Digital transmission through sliprings
is used in the data acquisition system. Various transducers are available
for measuring strain, displacement, pore pressure, load and acceleration
of the tested model. Data collection, transmission and processing are automatically
performed through the data acquisition program. Many model tests in this
laboratory have proved that the LXJ-4-450 large Size Geotecnical Centrifuge
is an efficient and powerful tool for solving geotechnical problems.
