Introduction Motorized ball screw-type actuators are used to move and position many critical aircraft components, including wing flaps, elevators, tabs, slats, rudders, stabilizers, landing gear and a host of ancillary components. In most of these applications the actuators must function reliably to ensure the overall safety of the aircraft, and …

There are plenty of “dumb” systems out there which can press parts together. Pneumatics and hydraulics have been used to do just this for longer than most of us have been alive. Human operators, while not dumb, present problems of their own. Even if all of the factors outside of the assembly itself are performing as they should, even slight …

The quality advantages of using an electric servo press to crimp, join, fit, stake and bend components of medical devices are driving an increasingly widespread adoption of this technology in the industry. It really started with catheters that require a small metal tube to be crimped to a larger metal tube that connects to the flexible portion of …
There are many different ways of testing gears and the assemblies in which they are incorporated. Functional Gear Assembly Testing Functional gear assembly testing could be defined as a series of tests that simulate the intended function of the product in an effort to determine whether an assembly operates within a specified performance …

Lithium Ion Batteries Lithium ion batteries (Li-Ion) are the technology of choice for applications ranging from handheld electronics to “plug-and-drive” vehicles, as well as back-up power systems used by “server farms” and other critical systems. Their performance characteristics are the result of a very delicately balanced set of chemical, …
