The authors tested the recommendation that adding bells and whistles (in the form of background music and/or sounds) would improve the quality of a multimedia instructional message. In 2 studies, students received an animation and concurrent narration intended to explain the formation of lightning (Experiment 1) or the operation of hydraulic braking systems (Experiment 2). For some students, th...

Aircraft Arrester Barrier Systems (AABS) are installed at the end of the runway to overcome the runway length on war ships. This system is used for the purpose of stop the combat aircraft due to aborted take-off and emergency landings. The conventional AABS is uncontrolled and highly non-linear system during the operation of aircraft arrestment system. Energy absorbing system is an important pa...

Hybrid vehicles usually have several braking systems, and braking mode switches are significant events during braking. It is difficult to coordinate torque fluctuations caused by mode switches because the dynamic characteristics of braking systems are different. In this study, a new type of plug-in hybrid vehicle is taken as the research object, and braking mode switches are divided into two ty...

We present requirements and success criteria for the realworld problem of (off-board) diagnosis of the hydraulic circuit of an anti-lock braking system. The primary problems to be addressed are quite fundamental: First, it is practically impossible to predict the dynamic behavior of this controlled automotive system as it depends on a number of unknown context conditions. Second, there are no d...

This paper describes in detail three kinds of typical compound braking strategy of wheel motor drive electric vehicle and summarizes the current commonly used strategies based on the three typical strategies developed. In the end, a new compound braking strategy is proposed; that is, we take braking mode classify, ECE regulations and SOC value of the battery as an important reference of braking...

Three-dimensional numerical simulations are carried out by commercial software STAR-CCM+ to investigate the hydraulic transient and flow behaviours of a prototype pump-turbine during the normal shutdown process. The global characteristics and pressure fluctuations are analysed as the pump-turbine runs through the turbine mode, into the turbine braking mode, and finally into the reversed pump mo...

This paper focus, on the various stages involved in the development of automotive embedded control system. Various V-models (SIL, MIL, and HIL) are compared with the proposed V model for hydraulic Antilock Braking System. The various tools available at different levels of the V model development phase have been analyzed. Model in loop `discussed in detail and further steps involved in the HIL s...

Any variable frequency drive requires an efficient and controlled braking system. Therefore, different braking techniques have been the subject area of researchers to enhance the performance as well as overall life of the drives. In this paper, a literature study is made of various existing braking methods, focused on induction motor (IM) drive performance. The braking methods are compared and ...

This paper is concerned with full vehicle nonlinear active suspension systems, in which each suspension unit consists of three components: a nonlinear spring, a nonlinear damper and a nonlinear hydraulic actuator. An artificial intelligence Neural Control technique has been presented in this paper to design a robust controller for full vehicle nonlinear active suspension systems. The advantage ...
