Statistical Summary

On the basis of analyzing the defects of existing design methods of cable wiring, the feasibility of interactive cabling design in virtual environment is pointed out. Based on the discrete control point, the geometric shape modeling method and the topological structure matrix modeling method based on the wire unit are presented. Adopt the method of real-time interactive cable modeling and wiring, explains the wiring process and control point positioning technology, and through the stratified multistage collision interference detection technology improve the authenticity of the wiring process and results. After the wiring design is completed, the statistical summary of the model information is compiled to generate various inventory reports to guide the actual production.

Practical Guidelines

Flexure hinges, which serve as the crucial joints in a large number of compliant mechanisms, have been widely applied in a variety of significant fields where there is high demand for the micro/nano motions with high resolution and high precision. Currently, an increasing number of notched flexure hinges with different structures and performances have been rapidly developed, but the existing performance comparisons on different notched flexure hinges were only conducted on seldom typical structures and are far from the comprehensiveness and fairness due to the different comparative conditions and discrepant evaluating indexes. Therefore, the finite beam-based matrix modeling method and nondimension precision factors will be employed in comprehensive comparing and ranking of 13 types of frequently-used notched flexure hinges in terms of their main compliances, motion accuracies, and stress concentrations, further providing useful practical guidelines to develop the compliant mechanisms with excellent overall performances.

The 20 KV PMT (Circuit Breaker) is an important equipment for the reliability of electricity distribution. Therefore it must be maintained so that it is always in good condition with regular maintenance. Prior to maintenance, PMT is terminated from the bus bar, which is called the rack out process. After maintenance, the PMT is reconnected with the bus bar, which is called the rack in process. Usually, 20 KV PMT rack in and rack out process in maintenance or disturbance is still using the manual method. The 20 KV PMT can only be racked in and racked out in one way, by turning the lever. The lever will rotate the bolt as a PMT rail. In the manual method, there is no system for monitoring the condition of the bus bar whether it is has electric-voltage or not. There is also no remote control that can rack in and rack out. So officers must ensure the conditions of PMT and bus bars are safe manually, before maintenance is carried out. This is quite troublesome and dangerous for officers. From these problems, in this research  designed a system that could ensure the condition of the PMT and the bus bar was safe before the rack in and rack out process was carried out and could monitor and control the system remotely using SCADA. Rack-in and rack-out automation system using VT SCADA, using Ethernet Shield that has been connected with Arduino Mega. Ethernet is connected to a mini PC. The microcontroller pins will be connected to the relays that will turn or stop the motor. The rack in and rack out commands from VT SCADA will determine the rotation of the motor so that the PMT moves. The current sensor reads the current flow and detects interference. Interference detection will automatically make PMT Rack out. System testing shows that the process of racking out in a state of maintenance or disturbance can be carried out automatically controlled by VT SCADA. Current sensor works to detect the current flowing, so that it can detect PMT interference and perform automatic rack out. The rack-in process is also capable of being remotely controlled with VT SCADA. This makes it easier for officers to also become additional reliability of PMT in the 20 KV cubicle.

This paper presents a new modeling method and a control system design procedure for a flexible rotor with many elastic modes using active magnetic bearings. The purpose of our research is to let the rotor rotate passing over the 1st and the 2nd critical speeds caused by flexible modes. To achieve this, it is necessary to control motion and vibration of the flexible rotor simultaneously. The new modeling method named as Extended Reduced Order Physical Model is presented to express its motion and vibration uniformly. By using transfer function of flexible rotor-Active Magnetic Bearings system, we designed a Local Jerk Feedback Control system and conducted stability discrimination with root locus. In order to evaluate this modeling and control method, levitation experimentation is conducted.
