Rotor and touchdown bearing models
Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor.
Fig. 1. Rotor under investigation.
In this work, the finite element model of the rotor employs…
Design and Simulation of Microcantilevers for Sensing Applications
MEMS is the integration of active and passive elements on a single chip, which combine electronics, electrical as well as mechanical elements to use in sensing and actuation. MEMS technology used in sensing applications with use of basic mechanical elements such as microcantilevers, beams, diaphragms, springs, gears and so on. In this research paper, microcantilevers are used as basic elements for design of Sensors.…

Why do you wish to become a Cathay Pacific pilot?
Becoming a pilot is my long-time dream.
As a young boy, I have always been curious about the mechanics of appliances. I often break the parts up — challenging me to know the ins and outs. The best part of it is putting it back together or solving the faults giving me a great sense of achievement. My secondary school was near the Kai Tak airport where I watched take-off and landings and listened to the roaring of the jets every day. This…
To assure the effective performance of controller over wide range of system operations and to increase the transient stability of the system, a supplementary fuzzy logic controller (FLC) based on the Mamdani's fuzzy inference method is designed for the PI controller input. FLC generates the required small change for voltage to control the magnitude of the injected voltage. The centroid defuzzyfication technique is used is this fuzzy controller.
The below fig describes the FLC structure. In this…

The inventor Nikola Tesla lived from July 10, 1856 to January 7, 1943, he was a well-known engineer who designed the alternating-current (AC) electric system. He was born in what is now Croatia; he came to the United States in 1884 and worked for Thomas Edison for a while before they both went their separate ways. Tesla sold several patent rights to George Westinghouse; one of those was his AC machinery. During Tesla’s career he discovered, designed and developed ideas for a number…
Thermosel Stainless Steel Bellow Expansion Joint was designed to utilize the piping system and to monitor the thermal expansion or terminal movement where the utilization of extension circles is undesirable or unreasonable. We offer this Thermosel Stainless Steel Bellow Expansion Joint that can prevent the unnecessary damage caused by vibration, pressure thrust, thermal growth, and other mechanical issues that can affect to the piping system.
These Expansion joints are uniquely intended to…
