The Types of Test Rigs Revealed

The increased requirements for reliability, durability and quality of functioning of automation, computing, radio devices and engineering products forces the manufacturers to perform various tests in conditions close to operational. To this end, research institutes and experimental production centers created a good number of special test rigs designed to simulate external influences. Unfortunately, testing the units in the real operating conditions is not only a very difficult, but also a resource-intensive process, deprived of profitability.

Climatic test typically implies using following test rigs:

  • thermostatic chamber to identify the impact of the results on elevated and low temperatures;
  • humidity chambers;
  • hyperbaric chambers to determine the effects of high (low) pressure, oftentimes used aviation and aero tooling;
  • thermo-humidity rigs to test the combined effect of temperature and humidity
  • thermal vacuum chambers to test the combined effect of temperature and pressure
  • special chambers to simulate solar radiation, dust and mist effects
  • special chambers to determine the impact of the results of bacteria and microorganisms.

Stability requirements to articles made with respect to mechanical stress have significantly tightened over the past years. This is due to the increase in speed and acceleration of moving objects the devices are transported with and working on. Mechanical loads cause deformation and breakage of individual parts and components like nothing else, developers have to be extremely accurate when determining the actual mechanical loads on the product to ensure trouble-free operation under real operating conditions.

Graphene: The Latest Advances

Both graphene companies, like 2-DTECH, promoting the numerous graphene uses, and researchers, like a Swiss-based EMPA, digging deep to discover new properties of the material, are grinding away to make another industrial revolution happen sooner than expected.

Thus, a group of savvy Australian and Irish scientists led by Gordon Wallace of Wollongong University, located in Australia, have managed to create grahene fibers, boasting record capacity ever achieved with graphene-based fibers.

he materials with similar capacity can be used as a supercapacitors, as their ability to accumulate electrons allows storing substantial amounts of energy which can be quickly applied, if necessary.

To produce graphene fibers a wet spinning method is used, which allows obtaining porous, yet extremely strong fibers of virtually any length. The fiber is made of graphene oxide and reduced graphene oxide, and the capacity of devices created using this fiber type is more than one and a half times higher than the previous record. However, according to calculations provided, the numbers can experience further growth. (more…)
