  • LMS Engineering Services Performed a Modal Test Campaign on Goodrich Landing Gear for the Airbus A380
    . The equipment also controlled the excitation management of shaker systems.Verifying the validity of the modal test set-upTo be able to provide sufficient energy while performing modal tests on a specimen of this size and weight, LMS engineering consultants installed multiple shakers. Two electro-dynamic shakers
  • AleniaAermacchi increases Testing Productivity with LMS Test.Lab
    of multiple test applications into LMS Test.Lab helps them efficiently run any kind of structural, modal, operational modal or environmental test assignment. In this way, Aermacchi is able to tackle operational in flight tests on a highly advanced M346 trainer prototype just as easily as executing vibration
  • The Twists, Turns, Trials and Tribulations of Your Average Material
    time and time again.  Only a hardness test can provide the needed results for crankshaft testing. To test the flexibility of a substance and its overall ability to stand up to tension, engineers perform tensile tests. These tests differ from impact and hardness tests in that applied force

    and powerful test result. presentations. Scalability through several. extension stages. Enjoy the flexibility: PAK Mobile MK II. is available in 2-, 3-, 4-, 6- and 10-slot. versions, and configurable with nearly no. limits in selecting the number of measure-. ment channels. New controller generations
  • Fatigue and Impact Testing of Composites Keeps Aerospace Industry Flying High
    to the chicken test gun.  This prepared hailstone is then fired at the test specimen at a variety of high speeds. More conventional impact tests are also used.  These methods utilize conventional impact test instruments, including pendulum style impact testers and drop weight test instruments.  More and more
  • Spinning Mass Mechanical Gyroscopes
    . Serson, an English scientist, noted in the 1740's that the spinning top had a tendency to remain level, even when the surface on which it rested was tilting. He suggested that sailors could use it as an artificial horizon on ships. Unfortunately, when Serson went to sea to test this idea the ship sank
