A cost-effective approach for the development of an integratedPC-PLC-robot system for industrial engineering education

Advanced manufacturing technology (AMT) instruction is and is likely to remain an important component of the industrial engineering education curriculum. As new manufacturing technologies become available and as existing manufacturing technologies become more integrated, industrial engineering departments must continuously develop their laboratory resources in order to provide their students with effective instruction. While financially limited departments cannot acquire state-of-the-art manufacturing equipment, they can provide improved hands-on AMT integration instruction without major capital investment. By developing an interface box between existing LabVolt PLC trainers and Microbot TeachMover robots, the industrial engineering department at a major Northeastern US university was able to provide its students with improved AMT integration instruction

Advanced gear-shifting and clutching strategy for a parallel-hybridvehicle

In parallel-hybrid electric vehicles (HEVs), both the electric drive and the internal combustion engine provide driving torque to the wheels either separately or together. The electric drive also can be used as a generator to recharge the batteries when the engine produces more power than is needed to propel the vehicle. As a result of the battery peak power density requirement, the vehicle needs a multispeed transmission between the electric drive and the main differential. In addition, due to the load sharing between the two independent driving sources, a clutch to separate the internal combustion engine and electric drive from the drive shaft is also required. Because the shift quality is directly related to the driving comfort of the vehicle, it is important to reduce both shift shock and time. To enhance the shift quality, we have proposed the advanced gear-shifting and clutching strategy for a parallel-hybrid drive train with an automated manual transmission (AMT). By using the electronically controlled AMT, users can achieve the optimal gear shifting, with regard to the efficiency of the hybrid drive train. Owing to the speed control of the induction machine and the diesel engine at gear shifting, the synchronization is always guaranteed and it reduces the shift shock and shortens the shift time. The dynamo-based experiments have been carried out for the purpose of proving the validity of the proposed transmission and clutch control in parallel-hybrid drive trains     

Knowledge-based gear-position decision

Gear-position-decision (GPD) tactics strongly affect the performances of automatic transmissions (AT) and, therefore, the performance of the vehicle. Since the electronic control methods were introduced into ATs, many advanced techniques have been raised to make AT vehicles more human friendly and better in fuel economy and dynamic behaviors. As a type of emerging AT, the automated manual transmissions (AMT) are being researched and developed in all relevant technologies. In this paper, we proposed a driving knowledge-based GPD (KGPD) method for AMTs. The KGPD algorithm is composed of a driving environments and driver's intentions estimator, the shift schedules for each typical driving environment and driver's intention situations, and an inference logic to determine the most proper gear position for the present situation. The estimator identifies the driving environments and features of driver's intentions, which are divided into some typical patterns. Based on the identified results, the gear-position inference algorithm calculates the best gear position at the moment. In fact, the method just simulates the course of a driver's making gear-position decision when driving an automobile with manual transmission. The test results show that the AMT with the method gives less unnecessary shifting, conducts more proper gear positions, and behaves better in subjective assessment than that with the method that is directly based only on automotive state parameters.     

TLM modelling using an SIMD computer

A major limitation of the transmission-line matrix (TLM) method used to solve Maxwell's equations is the long computation time required. The TLM scattering calculations involved can, however, be viewed as parallel in nature. This paper describes an effort to reduce computational time by using an SIMD, DAP multiprocessor computer employed to solve a two-dimensional TLM electromagnetic field formulation. A parallel algorithm based on the TLM scattering algorithm is designed and implemented using FORTRAN- PLUS Enhanced on an AMT DAP 510 machine. Here the connectivity of the DAP is exploited to simulate the intrinsic scattering behaviour on which the TLM algorithm relies. The results show that parallel processing on an SIMD machine such as the DAP is advantageous, especially for higher-order mesh sizes.

基于神经元PID的磁粉离合器电流控制

因为磁粉离合器的传递转矩与励磁电流呈线性关系,而且易于实现电子控制,故越来越多地应用在微型车上。针对装有磁粉离合器的电控机械式自动变速器,设计了磁粉离合器的驱动控制电路。由于驱动电路存在非线性以及汽车运行时复杂环境的干扰,应用传统的PID控制难以在控制参数整定上达到最优,为此提出利用具有自学习和自适应能力的神经元来构成磁粉离合器的自适应控制器。实验结果表明,基于该方法的磁粉离合器驱动控制动态效果较好,且系统具有较好的自适应性。     

Demonstration of Loss‐reduction Effect of the Amorphous Cores for Larger‐Capacity Transformers by Trial Manufacture

For the demonstration of feasibility and loss‐reduction effect of the larger‐capacity amorphous core transformers (AMT), this paper proposed the support structure and design method of the iron‐loss reduced amorphous wound cores with a weight of 7 tons. We designed and manufactured 10 MVA single‐phase test model with the cores inserted in a support cage having structures of the stress‐buffered core support, the proof electromagnetic force from the windings, and the stray loss‐reducing shields. The 50%‐loaded total loss of the test model estimated from the calculated and measured results has been reduced by 35% compared with a conventional silicon‐steel core transformer (SST) with the same power capacity.
