Risk Assessment of Transition to Lead-Free Electronics Assembly

The European Union’s Restriction on Hazardous Substances (RoHS) Directive, imposed on electronics manufacturers in 2006, banned the use of certain toxic substances such as lead and cadmium in components and assemblies. Removal of lead which was used in solder, die...

Calibrating Cyber Security Risks

Hardly a day goes by anymore without hearing about a cybersecurity event in the news. In this paper/session, we will analyze the risk associated with smart devices, calibration, and maintenance that could compromise the cybersecurity status of operations and possibly...

An Analysis of the Different Aspects of Intelligence in Machines

The purpose of this research paper is to technically and philosophically analyze the behaviors of the current intelligent machines and try to think about an eventual artificial evolution. Will Artificial Intelligence (AI) bring us more advantages or more...

Practical Rotor Dynamics for Users

Following a brief overview of the history of the development of key aspects of rotor dynamic technology, this paper describes ways to estimate critical speeds, and cipher them from resonances and other vibration phenomena. The influence of various bearing types on a...

Rolling Bearing Fault Feature Extraction of Casing Vibration Signal

The health of rolling bearing plays an important part in the operation of rotating machinery like a gas turbine engine. Health monitoring and fault diagnosis of rolling bearings based on vibration signals have been through great development these years. But when...

Gas Turbine Fault Detection Using A Self-Organizing Map

Turbomachinery condition monitoring and fault detection in the Malaysian oil and gas industry is currently done by monitoring the parameters of the equipment, such as a gas turbine, based on limits provided by the original equipment manufacturer. This is performed in...

Bolted Structural Connections In Fiberglass Materials

This paper compares several methods of connecting fiberglass-reinforced pultruded plastic (FRP) structural members to tubular sections using bolted designs that are commonly used in the cooling tower industry. The study compares theoretically predicted values with...

Universal Vibration Sensor Mount

The present paper describes universal vibration sensor mount devices for attaching sensors to the machinery. Some types of machinery vibration sensors need to be mounted in a particular orientation relative to the machine being monitored. One example is the two-axis...

Motion Amplified Video Application To Machinery Diagnosis

Vibration detection can be performed by a meter or a single channel spectrum analyzer. The former has quantified vibration amplitude levels since the 1950s, while the latter was able to implement the Fast Fourier Transform (FFT) since the 1960s to break vibration down...

Electrically Improving a MEMS Sensor for Rolling Stock

This paper describes work related to improving the electrical performance of an accelerometer-based sensor, RotoSense™, used for monitoring rolling stock: the locomotives and cars used in trains. At the 2018 MFPT conference, a paper, “Improved RotoSense™ for Rolling...

Motion Magnified Video Application To Machinery Diagnosis

Rapid Impact™ Testing Of Any Size Structure

One of the limitations of conventional modal testing using a roving impact hammer is that the reference sensor (usually an accelerometer) must remain fixed throughout the test. Since the accelerometer must typically be connected by a wire to the data acquisition...
