- Durability Testing Case Study
  December 13, 2018Blog / Products / Transducers / Wheel Force TransducersWhen it comes to innovation, Michigan Scientific Corporation (MSC) is always at the forefront of cutting-edge vehicle design and testing. With a new ISO 9001 certification, MSC Wheel Force Transducers (WFT) are used in a variety of testing applications on many different types of vehicles. From heavy duty trucks, to small and agile ATV’s, the MSC WFT is the first choice in specialized testing and measurement applications, such as rigorous durability testing. What is Durability Testing? Durability testing is a crucial component to the design and validation of a vehicle and the components. It is used to determine the expected life, as well as improve design. Wheel Force Transducers are an integral part of durability testing. Michigan Scientific designs and manufactures durable and reliable transducers that can be used in any environment, on the proving ground or in the lab. They provide all wheel force and moment data along with acceleration, wheel speed, and wheel position, which can be used for validation or to improve future vehicle configuration. A video of MSC Wheel Force Transducers being used during durability testing for electric vehicle development is shown below: Not only are WFTs an essential tool on the track, they are often used for public road durability testing, providing real environmental results. One aspect of public road durability testing is measuring the response from a vehicle when it drives over a pothole. Pothole Case Study Shown below is actual data from a pothole test. This graph displays data gathered during an event in which an SUV’s right front wheel hit a pothole at 25 miles per hour (MPH).This is a typical output that one may see during pothole testing. Since this is a real environment application, the event happens very quickly, at under 0.5 seconds. The weight of the vehicle is just under 1500 lbs, shown in the beginning of the data in the green Radial Force Magnitude, with the Fz Vertical Force underneath. The vertical force then drops when the wheel enters the pothole and is free falling. Upon making contact with the bottom of the of the pothole, the force returns to the approximate weight of the vehicle, just under 1500 lbs. The largest event happens when the wheel exits the pothole. There is a large increase in the force as the wheel comes in contact with the edge of the the pothole. As the vehicle suspension system responds to the impact of the pothole, the force fluctuates, until it returns to vehicle weight towards the end of the data set. A pothole test is just one of a multitude of different tests that utilize Wheel Force Transducers. Having a durable and accurate measurement system is crucial for studying how a vehicle responds to various road conditions.

- Long Lasting Slip Ring Technology
  December 4, 2018BlogFinding the right instrumentation for a testing project can be difficult. Finding the right instrumentation that will last a long time can be even more challenging. Michigan Scientific (MSC) offers precision instrumentation for a variety of applications, as well as reliable customer service. It is crucial that customer tests are not delayed or impacted because of faulty instrumentation or poor customer service. Michigan Scientific stands by the quality and workmanship of all MSC equipment. Because of this, MSC offers a one year warranty on slip ring assemblies if there is an issue with the product workmanship. Additionally, Michigan Scientific inspects returned slip ring assemblies, free of charge, and recommends any cleaning or maintenance. This regular maintenance helps increase the life of the slip ring assemblies and decrease any downtime during testing. Real Example MSC was reminded again of the importance of continuing to produce quality instrumentation with reliable customer service. A B4-2 Tubular Slip Ring Assembly, shown in the image above, recently came back for inspection after being in the testing field for 18 years! It was put through years of rigorous testing on agriculture equipment. Since the customer had returned the slip ring for regular cleaning and inspections, it operates like it did 18 years ago, giving accurate and dependable signal transmission during in-field testing. About the Slip Ring Tubular Slip Ring Assemblies are a versatile product that are used to make connections to strain gauges, thermocouples, ICP accelerometers, RTD’s and other sensors in rotating applications. The Tubular models mount over a shaft, and are ideal for applications where an End of Shaft Slip Ring Assemblies cannot be used or space is limited. The B4-2, specifically, mounts onto shafts up to two inches in diameter and provides four slip ring connections. All tubular assemblies are available with an optional encoder. To learn more about which slip ring assembly is best for your testing application, contact a Michigan Scientific representative today....
