  • Crash Walls

For general automotive testing solutions, key considerations for auto testing lab requirements are high cycle count capabilities and load cell integration in actuation systems. Our products are used for off-axis and impact loading and measuring test article failure net results. The equipment can be exposed to many environmental challenges so load cell ruggedization is very important to lab professionals.

Automotive Driveline Test Types

  • Engine and Motor Performance and Durability Tests
  • Engine and Motor Efficiency Testing
  • Power Analyzation (Electric)
  • Driveline Durability and Efficiency
  • Component Testing
  • Accessory Drive Testing

For automotive driveline testing, considerations on equipment include peak torque ratings, rotating torque capabilities. Easy transducer integration with couplings matters for these tests. Additional factors for equipment include signal requirements, environmental conditions, noise levels, both electrical and mechanical and vibration. The devices used in testing article failure are very important for evaluating net results.

Test labs also prefer precision sensors for critical tests, which include our 1200 Series LowProfile™ Load Cells with their special moment compensated design. Popular ruggedized Interface products used in automotive testing include our 2400 series and 3200 series Stainless Steel LowProfile™ Load Cells and our WMC Miniature Load Cells

Maritime Measurement Solutions for Onshore and Submersible Applications

Maritime test and measurement applications are some of the most unique because they require specially designed equipment that can handle the often-harsh environments in testing, and during ongoing operational use.

The solutions for the maritime industry require technologies that measure force, torque, and weight under extreme and uncommon conditions. Interface provides products that have been used for withstanding the rigorous requirements of monitoring underwater tension lines, seaborne components and material testing, boat and ship engine testing, equipment durability and safety regulation monitoring, lift capacity measurements, energy extraction equipment, and storm and tsunami monitoring.

We have been a long-time supplier of sensor technologies and instrumentation that are applied in building and maintaining boats, yachts, and other water vessels of all sizes. Our force measurement solutions are used for waterborne vessels, maintenance, safety equipment, and offshore products. You can learn more in our maritime case study here.

Interface offers a wide variety of submersible and wireless load cells, DAQ, and instrumentation products. Our rugged load shackles, load pins and tension links are very popular for maritime test and measurement applications. Maritime manufacturers and field users rely on these quality products as they are designed for test and measurement requirements onshore, near-shore, and completely undersea.

Force Measurement Solutions for Mobility Markets

One of the tenets in addressing urban mobility is innovation.  As populations grow around the world, addressing how people get from here to there is part of a challenge and opportunity.  Investments are growing in this sector, as experts and designers look to how to increase efficiency and performance in vehicle markets.

Interface has long been a supplier of test and measurement solutions to industries that play a critical role in mobility, from vehicle manufacturers to infrastructure planners and builders. In our latest case study, we look at some of the innovative ways our solutions are being used to advance technologies and capabilities in transportation.

If something moves, it likely needs force and torque testing for reliability, safety and performance. With the evolving trends in urban mobility, Interface is working with makers and builders of all types of transportation solutions for unmanned vehicles like drones and autonomous vehicles, as well as alternatively fueled and electric vehicles.

READ OUR NEW CASE STUDY: INTERFACE’S CRUCIAL ROLE IN VEHICLE AND URBAN MOBILITY MARKETS

Interface customers utilize our standard and custom products in the vehicle and mobility markets to:

  1. Test the force and torque of components for validation or for design improvements
  2. Integration of sensor technology into a component or product for functional real-time performance data

These products include Interface load cells, mini load cells and subminiature load button load cells, rotary and reaction torque transducers, instrumentation, and accessories. For the growing trends for digital requirements in testing and OEM solutions, our wireless and Bluetooth solutions are commonly used in these markets.  Interface is also frequently engaged on specific customer requests for engineer-to-order products and customized solutions.

Here are four use case scenarios of Interface solutions used in the vehicle and mobility markets:

Brake Pedal Testing

Interface’s Brake Pedal Load Cell BPL-300-C was installed on a brake pedal and then connected to a BTS-AM-1 Bluetooth Low Energy Strain Bridge Transmitter Module, which collects and transmits data to our BTS Toolkit Mobile App. This solution allowed the customer to record and review data from a mobile device while out on a test track. READ MORE HERE.

Drone Delivery Systems

Interface supplied four WMC Sealed Stainless Miniature Load Cells to measure the payload weight and  for the detection of in-motion shifting and uneven distribution of the package weight. As the load cells detect this data, it provides a signal to the propeller to increase RPMs on the propellers and adjust balance and weight distribution inflight. WATCH HERE.

Electric Vehicle (EV) Battery Testing

Compression testing performed on EV batteries is critical for performance and safety. As an EV battery is charged and stores more electrons, it swells. If the packaging housing the batteries does not compensate for this swelling in the design, failure is likely. Interface can supply a WMC miniature load cell. The load cell will measure compression force as a battery goes through charge cycles on a test stand to determine the force given off as the battery swells. This allows our customers to design the proper packaging for the batteries. Read more about the future of EV markets and testing here.

Engine Performance Testing

Force and torque sensors are used with a dynamometer, which isolates the engine’s power output to help quantify its overall performance.  In this application, a  precision SSMF Fatigue Rated S-Type Load Cell is attached to a torque arm to “feels” the torque from an engine loading system. The fatigue rating on the load cell allows it to accurately measure performance for extended cycles. A signal conditioner is used to connect out from the load cell to a computer to ensure clear transmission of data to accurately measure torque being produced by the engine. Engineers analyze power transfer through the data output to tune the engine performance. Check out this engine dynamometer application note here.
