A New Approach Combining Numerical Analysis and Three Dimensional Simulation for Design of Worm Gearing With Preferable Localized Tooth Contact

Volume 1A: 25th Biennial Mechanisms Conference, 1998

The approach consists of numerical analysis and three-dimensional simulation within an advanced CAE package. The numerical analysis secures the localised contact, which provides mathematical models and a numerical calculation procedure to determine the modification parameters for the PLTC. With the three-dimensional simulation, the tooth contact pattern at any instant and the moving direction of the localised contact area can be predicted; moreover, the interference between the modified tooth surfaces can be detected, and, hence, it can be avoided at design stage. The simulation proves that the PLTC is much less sensitive to the errors arising from manufacturing and assembly, which is beneficial for achieving a high transmission quality and cutting down the time and efforts spent in production and assembly.

A novel remote control system for air conditioning in low carbon emission buildings using sensor fusion and mobile communication technologies

Currently, however, its use is limited in high humidity areas due to low cooling efficiency and no effective method for controlling this type of system remotely. This research developed a novel remote-controlled system for use with airconditioning units utilising solid desiccant dehumidifiers which can be employed to create low carbon emission buildings. The system employs multiple information technologies such as sensor fusion, digital input/output communication and mobile technologies to monitor and control the internal conditions of air-conditioned buildings and provides data collection, data processing, system control, and mobile access. The data collection module is built based on sensor fusion technologies to detect the operating status of the conditioned air. The real-time data processing module is implemented with feature extraction and non-linearization computing to process received data and transmit commands to a control unit. A case study involved monitoring and controlling the working conditions of a solid desiccant dehumidifier employed in an air conditioning unit. Remote control of the process was performed by tuning a NI-DAQ controller's parameters to regulate humidity, temperature, flow rates and other conditions in the unit. A mobile phone was utilised to demonstrate the remote-control function. The results prove that the system developed is successful in controlling the operation of water-cooled air conditioning units.
