Dynamic Test

  • Friction Technology dynamometer is a device for measuring force, torque, or power.
  • For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (RPM).

Formulation

  • Our friction formulators have over 75 years experience in the friction material industry.
  • With over 60 friction formulations available our comprehensive range covers virtually all types of industrial applications
  • Latest innovations include the following:
    • Noise free composite materials for wind turbine brakes
    • Organic semi metallic for static holding
    • Sintered friction for high speed dynamic applications.

Shear Test

  • Shear is defined as the force that causes two contiguous parts of the same body to slide relative to each other in a direction parallel to their plane of contact.
  • Shear strength is the stress required to yield or fracture the material in the plane of material cross-section.
  • With current and evolving industry relying more heavily on composites and bonded materials, the need for reliable and accurate shear testing is at an all-time high.
  • When parts or processes in a production are subjected to shear forces or stresses, quality control programs should include shear testing to ensure that processes are optimised and parts are safe.
  • Fortunately, with the proper knowledge and test methods, shear testing can be performed accurately and reliably in a common laboratory setting.

SolidWorks

  • SOLIDWORKS solid modelling computer-aided design and computer-aided engineering software covers all aspects of our process and product development with a seamless, integrated workflow—design, verification, sustainable design, communication and data management.
  • SOLIDWORKS provides our customers with the following benefits: 
  • Seamless transfer of customer CAD drawings to our CNC manufacturing plant reducing lead times and eliminating errors
  •  Verification of customer requirements where no drawings are available e.g. from samples 
  • Design, simulation, and manufacturing of bespoke jigs and fixtures maximising productivity and product quality. 
  • We are able to shorten the design cycle, increase productivity and deliver innovative products to market faster 
  • The SOLIDWORKS Simulation package enables us to simulate to real-world conditions and raise the quality of our products while reducing costs for live prototypes and testing. 
  • Enable us to validate that systems will work and continue to refine their commercial application.

Test Bench

Test specification

  • Fatigue Test: consists on a static test to simulate the life of the different parts of the brakes including seals, pistons and brake housing. This function is controlled by the PLC providing different cycles at high pressure (180 bar) and low pressure (20-40 bar) simulating a real application on a wind turbine.
  • Friction Material Wear Rate: consists in a dynamic test where hydraulic pressure is applied into the brake(20-40 bar) and the cylinder provides a movement to the plate/disc simulating the real Yaw movement in the wind turbine, after XXX cycles wear rate of different friction materials can be verified.
  • Friction Material Coefficient: consists of a dynamic test and static test:
    • i. Static test, high pressure is applied into the brake (standard parking position in a wind turbine) and gradually the pressure is increased in the cylinder, when the plate/disc starts the movement PLC will calculate the static friction coefficient.
    • ii. Dynamic test: Hydraulic pressure is applied into the brake (20-40 bar) and the cylinder provides a movement to the plate/disc simulating the real Yaw movement in the wind turbine, PLC will calculate dynamic friction coefficient.
  • Noise/Vibration Test: consists on the application of hydraulic pressure into the brake (20-40 bar) and the cylinder provides a movement to the plate/disc simulating the real Yaw movement in the wind turbine, during such movement noise/vibration appears and it’s measured by a vibration control device.
