The invention provides a piece of power splitting tension loading
test equipment suitable for CT scan. The equipment comprises the following components: a pulling
force platform, a pulling and pressing converting mechanism, a pressure platform, a
universal joint, steel poles, a test piece, a constraint platform, a pressure and displacement sensor, and a
computer control system. A test piece is clamped between the constraint platform and the pressure platform; the
universal joint guarantees realization of parallel pressurization; the pressure platform and the constraint platform are connected into a reaction frame through the steel poles, in order to form a self-balance
system; the pulling
force platform and the pressure platform are connected by the pulling and pressing converting mechanism, in order to realize conversion from pulling force load into
pressure load; the pulling
force platform is externally connected to a hydraulic elongator, in order to carry out application of dynamicloading; the load and displacement sensor, and the
computer control system can guarantee loading mode and
loading rate of the test, and at the same time experiment data is recorded. The equipment hasa small volume and is convenient for movement, and can be placed in a detection scope of a medical X-
ray CT
machine, in order to realize synchronization of measurement and loading, and effectively solve the problem of synchronous recording of
crack initiation in the splitting tension test process.
