Piezo Engineering Tutorial

1.0 The Direct and Inverse Piezoelectric Effect In 1880, while performing experiments with tourmaline, quartz, topaz, cane sugar and Rochelle salt crystals, Pierre and Jacques Curie discovered that when mechanical stress was applied to a crystal, faint electric charges developed on the surface of that crystal. The prefix “piezo” comes from the Greek piezein, which means to squeeze or press. As a result, piezoelectricity is electrical charge that is produced on certain materials when that material is subjected to an applied mechanical stress or pressure. This is known as the direct piezoelectric effect.

Why bigger isn’t always better: the case for thin section bearings

For applications that demand maximum performance despite space and/or weight restrictions, designers should consider thin section bearings. While conventional bearings often have more load capacity, thin section bearings have more than enough for a wide range of applications and offer exceptional design flexibility with opportunities for significant reductions in overall system size and cost. A new white paper from Kaydon Bearings, an SKF Group company, examines thin section bearing styles and features, with a discussion of design considerations, fit, lubrication, and other useful information.

Reverse Engineering

Finding replacement metal bellows components is easier with Servometer's time saving reverse engineering guidelines. Download White Paper Reverse Engineering guidelines Today's design engineers often find themselves in the uncomfortable predicament of replacing legacy parts or parts that have become obsolete. This predicament is often the result of undocumented drawings, part numbers, or specifications. In many cases, the original designer is no longer available. Whatever the reasons, it is often the job of the design engineer to propose a solution using outdated technology and resources or insufficient information. This paper offers hands on reverse engineering guidelines and provides a solution to finding the ideal replacement bellows for your application.

Electroforming Basics

Electroforming is the process of depositing thin layers of metal onto a mandrel through electroplating, dissolving the mandrel chemically, and leaving the plating as the final electroformed product. Learn how electroformed components are manufactured and how they can be applied to a variety of applications.

Lubricant Selection: What Every Design Engineer Needs to Know

Simply stated, lubrication refers to the age-old science of friction reduction. People have been using lubricants for thousands of years, experimenting with waxes and oils from vegetables, fish, and animals to move heavy materials with equipment designed to gain mechanical advantage. In more recent years, the discovery of petroleum oil in the 1800s ushered in a new era of lubrication developments as people learned how to refine this oil and use it for a variety of purposes. Machinery could now be developed to operate faster and under heavier loads by using lubricants to create a barrier that eliminates friction and metalon- metal contact.
