Reduction Gearbox Motion Transmission Using a Crankshaft and Bellows

Approximate Incremental Dynamic Analysis Using Reduction of Ground Motion Records

Incremental dynamic analysis (IDA) requires the analysis of the non-linear response history of a structure for an ensemble of ground motions, each scaled to multiple levels of intensity and selected to cover the entire range of structural response. Recognizing that IDA of practical structures is computationally demanding, an approximate procedure based on the reduction of the number of ground m...

A skin indentation system using a pneumatic bellows.

A pneumatic indentation system using a copper bellows has been developed for physiological studies where a controlled uniaxial compressive force is required to be applied to the surface of the skin. Such a system is useful for studies where the physiological response of the tissues is to be monitored following a known loading history. The indentation system is driven by a vacuum/compression pne...

Characterization of Vibration Transmission Paths for Gearbox Condition Monitoring

For gearbox condition monitoring, the position of the accelerometers can be crucial for the detection of possible defects. However, little information can be found in the literature for engineers in setting up condition monitoring. This study is to investigate the characteristics of gear vibration and its transmission path for sensor placement and reliable fault diagnosis. Vibration sources pro...

Calculation and Measurement of the Crankshaft Motion In the Bearings of a Refrigeration Compressor

Transmission Network Reduction Method using Nonlinear Optimization

This paper presents a new method to determine the susceptances of a reduced transmission network representation by using nonlinear optimization. We use Power Transfer Distribution Factors (PTDFs) to convert the original grid into a reduced version, from which we determine the susceptances. From our case studies we find that considering a reduced injectionindependent evaluated PTDF matrix is the...
