Exclusive features, trends and insight from PD&D’s staff and elite industry contributors, keeping you informed on the latest innovations in design engineering.
The Weakest Link In Wind Energy Supply   3/19/2010
Converting wind energy to electrical power is the fastest growing segment of the U.S. energy sector. Bolstered by available federal stimulus dollars, there has been a virtual modern-day “land-rush” to develop wind farms. In the words of one industry leader, “If there is a site that has a viable wind profile, access to network connections, and access for delivery of materials, and we don’t develop it, someone else will.”   Continue
Specifying Linear Motion Products   3/18/2010
When applying linear motion components to your project, there are many options and considerations. Guide-rails and guide-ways are globally produced in differing forms to suit very specific engineered purposes.   Continue
Nano-Scale Imaging & Fabrication Advances   3/18/2010
Engineers from TMC and PI have developed active vibration isolation technology based on piezo ceramic solid state actuators that has become an established solution in nano lithography applications.   Continue
Energy Recovery Devices (ERDs) Make Desalination A Reality   3/16/2010
Currently, about 885 million people globally face water scarcity, and according to the United Nations, a child dies from water-related disease every 15 seconds. Clearly, the world’s water woes have reached crisis levels.   Continue
Know The Application   3/15/2010
Understanding the application is the single most critical element when specifying a linear actuator. By knowing the application requirements, design engineers will be best served when selecting the appropriate type of actuator. Whether it is a rod or rodless or screw or belt driven type actuator, application parameters such as the motion profile, desired speed, duty cycle, force, expected life and operating conditions need to be carefully considered.   Continue
Good Design Is A Touchy Subject   3/9/2010
The dominance of tactile properties in overall product performance varies widely, however. The sense of feel for one product may not rise to a conscious level for the user or it may dominate and define the overall experience.   Continue
When Words Collide   3/5/2010
“People are our greatest resource.” "people are our greatest asset.” This is what many organizations espouse every day. However, these words often don’t match the actions of an organization toward its employees. If you consider a person as a consumable item, then perhaps this perspective is valid.   Continue
I Have Seen Many Weird & Wonderful Things   3/3/2010
In the latest PD&D Fireside Chat, Wood taps into those 20 years to discuss bearing jokes, one-piece flow, silly ways to make money and the further weakening of the dollar — among other things.   Continue
Environmental Resistance, Long Life Make Linear Position Sensors Reliable Feedback Devices In Offshore Applications   3/2/2010
When designed and constructed to specific requirements, LVDT-based linear position sensors (see Figure A) can provide highly accurate measurements in environments with high pressure and corrosive atmospheres, both found in offshore and subsea applications. Offering friction-free operation, environmental robustness and unlimited mechanical life, linear position sensors offer a reliable and cost-effective choice for offshore applications.   Continue
Increasing Motor Efficiency With Power Factor Control   2/24/2010
“Global Warming, Carbon Footprint, and Energy Efficiency” are becoming mantras for the industrial manufacturing sector. With energy costs constantly rising leading to increased overhead costs, the need to use electrical energy in a more efficient manner by reducing the amount is at the fundamental basis of this crisis.   Continue
