There are several kinds of metrics should be handled by the brake system of hybrid electric vehicles such as fuel economy, performance and safety. The optimal control of the HEV brake system will be solved by a modelbased approach. Based on the developed vehicle model, a two phase approach is proposed for the coordinated control of the HEV brake system. A high level sliding mode controller is a...

Under continuous braking and long slope conditions of high intensity for a time, the temperature brake friction plate is extremely high, which leads to poor efficiency in process, even makes force completely lost, More more heavy-duty vehicles high-speed transport are equipped with retarders. As an auxiliary system, vehicle retarder can effectively maintain constant during braking. This paper d...

As part of ongoing research, a wheelchair dynamometer has been designed and built. This device is complex test stand, enabling research on the operation wheelchairs, taking into account number biomechanical factors in laboratory conditions. Based review available literature, braking system was constructed as drive system. resulted design issue concerning optimal selection electromechanical comb...

The paper includes the second part of an investigation of the braking process of railway vehicles, dealing with the temperature distribution of a brake block in various load cases and the FE analysis of the phenomenon of thermal elastic deformation. Thermal expansion calculations pointed out to the fact that in case of the contact area, the radius of the operating surface of the brake block inc...

Brakes and tires are the major contributors for catastrophic failure of ground vehicles. Braking system is the utmost important besides tire to ensure the safety of users and vehicle. Ensuring good condition of brake lining is very crucial to ensure the efficiency of the braking system, where, the worn off brake lining not only endangers life but also damages the entire brake associated parts s...

In the More Electric Aircraft (MEA), many subsystems that previously used hydraulic, mechanical, and pneumatic power have been fully or partially replaced with electrical systems. Particularly, this article discusses feasibility of an equipment intended for electric taxiing application. Namely a 35 kW DC-DC converter 2500 Wh storage unit targets recovery energy from aircraft brake restitution o...

in the present study, development of new asbestos-free brake pad using lingo-cellulosic fibers and nano aluminum oxide particles was investigated. variable factors were the type of lignocellulosic materials (jute, bagass and rice husk) and the size of aluminum particles (nano and micron). these newly formulated brake pads have been tested under the grey cast iron disc. friction coefficient and ...

To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...

INTRODUCTION Brake linings and brake pads are among the asbestos-containing products that are readily available in Colombia. When sold separated from their support, brake linings require extensive manipulation involving several steps that include drilling, countersinking, riveting, bonding, cutting, beveling, and grinding. Without this manipulation, brake linings cannot be installed in a vehicl...

Brake fluid is a mixture of different Glycol derivatives which are poisoning and their ingestion triggers significant CNS symptoms, severe metabolic acidosis, cardiac, pulmonary, and renal failure. Here in this study, a case is reported who had been ingested 150mL of brake fluid for suicidal attempt.
