Granular Shear Cell (GSC)

This granular shear cell helps to study the flowing and shearing behavior of grains between relatively moving surfaces. This cell allows one to study the grain flow velocity, solid fraction, granular temperature (i.e., velocity fluctuation), energy dissipation during flow, and slip velocities.

To impose shear on test grains within the GSC, the inner rotating wheel has can be given a prescribed roughness. The GSC has an aluminum frame with a transparent body so that the dynamic behavior of the grain flow can be observed using high-speed photography where the particle position and velocimetry data are known as a function of time. The moving wheel is attached to a 1/16 HP motor capable of achieving rotational speeds of 53–280 rpm, which corresponds to a linear velocity of 0.55–2.89 m/s.

Vision Research VEO–710S (High Speed Camera)

The VEO 710 is the fastest VEO model and features a one megapixel sensor with over 7 Gigapixels/second (Gpx/s) throughput. This translates to the ability to record up to 7,400 frames-per-second (fps) at its full 1280 x 800 resolution, or over 8,200 fps at 720p HD. The top speed at reduced resolution is 680,000 fps standard or 1,000,000 fps with the FAST option, which also provides exposure times as low as 300 nanoseconds. With the maximum RAM configuration of 72 GB, at 7,400 fps the VEO 710 provides over six seconds of record time.

Applications include multiphase flows, tribology debris generation, fluid dynamics, biomechanics, material test, airbag development and test, microscopy and granular flow. The high-speed CCD camera is used to capture images of granular flow data such as solid fraction, particle velocity, and slip.


Coefficient of Restitution Measurement (COR Rig)

Single granular particles can be dropped from various heights and COR based on height or velocity is computed. The apparatus is used to measure the coefficient of restitution (COR) between colliding materials.

The casing (E) provides holes that fix the suction device (F) in place at different heights. The air hose/pump (G/H) provides a suction force to the holding apparatus (F), which is turned on to hold a sphere (C) with holder (D) in place and then switched off to allow the sphere to drop from rest. This type of setup minimizes spin during the drop. The base plate specimen (B) is 15.24 cm square of various thicknesses and mounted on hollow metal support (A). The hollow block structure allows the flexural vibrations in the plate and it is sufficiently rigid to support the plate edges. In this way particle impact with finite and semi-infinite plate can be measured.

Four Ball Tester

The Four Ball Tester can be used to determine Wear Preventive properties (WP), Extreme Pressure properties (EP) and friction behavior of lubricants. A rotating steel ball is pressed against three steel balls firmly held together and immersed in lubricant under test. The test load, duration, temperature and rotational speed are set in accordance with standard test schedule. In Wear Preventive (WP) tests – also called Anti Wear (AW) tests – the average scar diameter on the bottom three balls is reported. The size of the scar shows the ability of the lubricant to prevent wear. A larger diameter indicates poor wear preventive property while a smaller indicates superior wear preventive property.

  • Single instrument for Extreme Pressure (EP) and Wear Preventive (WP) tests.
  • Built-in "Collet Master" attachment for sample loading.
  • Optical microscope included for scar measurements
  • Rotational speed :3,000 rpm (Max)

ExOne Innovent 3D Printer

ExOne uses Binder Jetting technology to 3D print complex parts in industrial-grade materials. Binder Jetting is an additive manufacturing process in which a liquid binding agent is selectively deposited to join powder particles. Layers of material are then bonded to form an object.

Binder Jetting is capable of printing a variety of materials including metals, sands and ceramics. Some materials, like sand, require no additional processing. Other materials are typically cured and sintered and sometimes infiltrated with another material, depending on the application.

Offering eight times the print volume of prior lab models and designed for research and educational customers, the Innovent® 3D printer is an excellent tool for developing powdered materials and processes, as well as training the next generation of manufacturing and material scientists, enabling the exploration of ExOne® technology under industrial conditions.
