Principle of Operation :

Operation of the machine is by hydraulic transmission of load from test specimen to a separately housed load indicator. The hydraulic system is ideal since it replaces transmission of load through levers & knife edges, which are prone to wear & damage due to shock on rupture of test pieces.

Load is applied by a hydrostatically lubricated ram. The oil pressure in the main cylinder is transmitted to the cylinder of the pendulum dynamometer system housed in the control panel, the dynamometer piston exerts a force proportionate to the hydraulic pressure. This force is transferred through a leverage system to a pendulum. Displacement of pendulum actuates the rack and pinion mechanism which operates the load indicating pointer.Return movement of pendulum is effectively damped to absorb energy in the event of sudden breakage of specimen.

Machine comprises of the following :

Straining Unit :

    This consists of a hydraulic cylinder & piston mounted on a robust base. The loading frame consists of an upper crosshead, middle crosshead and lower table
    The upper crosshead and lower table is connected by means of two plain hard chrome plated columns. The middle crosshead is fitted on two hard chrome plated threaded columns. A reduction gear motor drives the chain and sprockets fixed at the bottom of the threaded columns for height adjustment
    The cylinder and ram is individually lapped to eliminate friction. Axial loading of the ram is ensured by relieving the cylinder & ram of any possible side loading by the provision of ball seatings

An elongation scale with least count of 1mm is provided for measurement of deformation on various samples. Tension test is conducted by gripping the test specimen between the upper and middle crosshead. Compression, Transverse, Bending Shear and hardness tests are conducted between the middle crosshead and the lower table.

Control Panel :

The control panel consists of a power pack complete with drive motor and oil tank, control valves, a pendulum dynamometer, a load indicator system and autographic recorder.
