The lab is having experimental setup capable of catering from basic experiments for first year M.Tech students up to advanced test setup for research scholars.
HVGG is used for the study of dynamic indentation behavior for metal and alloys. The results obtained from HVGG is in the form of crater profile. The main property which is evaluated from crater diameter is dynamic hardness. Dynamic hardness with constraint factor (CF) gives the dynamic flow behavior of different metals and alloys at the strain rate of 10^4 sec^-1.
Hardness of a material is generally defined as Resistance to the permanent indentation under static and dynamic load. When a material is required to use under direct static or dynamic loads, only indentation hardness test will be useful to find out resistance to indentation. In Brinell hardness test, a steel ball of diameter (D) is forced under a load (F) on to a surface of test specimen. Mean diameter (d) of indentation is measured after the removal of the load (F).
To determine the hardness of the given specimen at different temperature using High temperature macro indentation test setup.
This test setup can simulate and detect vibrations in shafts, bearings and belts. Loads can be applied through compressor or dynamometer. It can be used to study the vibration isolation to the base. The vibration values can be recorded in Human machine Interface screen. The damping characteristics of the mounts can also be studied using this instrument. This instrument is solely designed and constructed by a PhD scholar from DIAT.
VFT is capable of a wide range of experiments covering all vibration concepts:
1. Lumped System Experiments
2. Continuous System Experiments
3. Vibration Control Experiments
It has the following features for experimenting:
Pendulum Vibration Module: Adjustable length and weight
Spring-Mass-Damper Module: Spring: Three different stiffness, stackable for 2 DOF, Mass: Three weights, stackable, Damper: One dashpot and three fluids.
Torsional Vibration Module: Shaft: Three different Diameters, Rotor: Three rotors of different mass and inertia, Damper: One damper and three fluids (optional).
Vibration Control Module: Tuned mass damper: Hardware for mass-spring absorber, and hardware for beam absorber Beam with damping treatment: One viscous-elastic layer and one constrained layer
Electrodynamic shaker is used to generate different kinds of vibration to a system fixed on its fixture table. Three tests are carried out on it. They are:
1. Frequency test
2. Shock test
3. Random test
It can test a sample weighing up to 15 kg and frequency ranging from 5Hz to 2000Hz.
