Safety critical systems are those systems whose failure could result in loss of life, significant properityda mage, or damage to the environment. Brake-by-wire (BBW) technology in automotive industry is the ability to contr ol brakes through electrical means. It can be designed to supplement ordinary service brakes or it can be a standalone brake system. The increasing usage of brake-by-wire sy...

The aim of this work is to develop a magnetorheological brake (MRB) system that has performance advantages over the conventional hydraulic brake system. The proposed brake system consists of rotating disks immersed in a MR fluid and enclosed in an electromagnet, which the yield stress of the fluid varies as a function of the magnetic field applied by the electromagnet. The controllable yield st...

A new, systematic approach to the design-evaluation-test product development cycle is described wherein the vehicle design and simulation environments are integrated. This methodology is applied to brake mechanical design and material selection. Time-domain computations within a vehicle dynamic simulation environment account for brake and lining geometry and material properties, actuator proper...

Brake oil is a type of hydraulic fluid used in automobiles. It consists toxic compounds like ethylene glycol, diethyleneglycol and additives. poisoning rare it can either be due to intentional or accidental1,2. Toxic manifestations are mainly metabolites rather than the brake oil3,4. Immediate haemodialysis other supportive carecan improve outcome intoxicated patients. Here we present case repo...

Brake-by-wire (BBW) technology is crucial in driverless cars. The BBW technology, which has a faster reaction time and greater stability, can improve passenger safety refers to the removal of some complicated mechanical hydraulic components from traditional braking system favor using wires transmit signals, improves performance. Firstly, this paper summarized BBW’s development history as well i...

This paper aims to provide a new design considering compressive force application in the MR fluid andimprove its braking torque by optimizing it. According current study, compressing region will increase compared no compression. The area covered an existing model of conventional disc brake is taken into consideration for unique operate shear and compression mode, required given hydraulic pressu...

This paper presents an experimental investigation of various exhaust gas recirculation (EGR) rates on the engine performance like brake thermal efficiency, brake specific fuel consumption and brake power and engine exhaust gas emission parameters like nitrogen oxides(NOx), carbon monoxide (CO), hydrocarbon(HC) and particulate matter (PM) for the fuel used in the engine. Four observations are ma...

Fault diagnosis method based on the moment characteristic of system pressure data is presented in this paper. Using AMESim simulation technology, three typical faults of the brake system are studied. After the moment and the percentile characteristics of the pressure curve of the hydraulic system are extracted and used as characteristic parameter, fault information is diagnosed effectively usin...
