Present cable trolley brakes used in material transfer or overhead trolley transport systems uses twin shoe caliper brakes operated by solenoid. These brakes are not fail safe, means that slip occurs between cable and brake caliper. Sometimes overloading leads to wear of brake shoe material. The failure of brake system may increase the chances to loss of life of occupant. These conventional cal...

For the safety problem of heavy duty vehicles running on long downhill sections, a model was built for the application of engine brake and service brake combination based on test results. And a model of brake temperature rise for heavy duty vehicles running on long downhill sections was also established. For different braking modes, gear positions, speed and downhill slopes, brake temperature r...

nitrogen oxides (nox) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. in-cylinder high temperature flame and high oxygen concentration are the parameters which affect the nox emissions. the egr system is a very effective way for reducing nox emission from a diesel engine (via reduction of these parameters), particularly at the hi...

A unique decoupling feature in frictional disk brake mechanisms, derived through kinematic analysis, enables modularised design of an Anti-lock Braking System (ABS) into a sliding mode system that specifies reference brake torque and a tracking brake actuator controller. Modelling of brake actuation, vehicle dynamics, and control design are described for a scaled vehicle system. The overall con...

Free-flow and stop-flow intratubular pressures were measured in rats with an improved Gertz technique using Landis micropipets or a Kulite microtransducer. In hydropenia, average single nephron glomerular filtration rate was 29.3 nl/min, glomerular hydrostatic pressure (stop-flow pressure + plasma colloid osmotic pressure) was 70 cm H(2)O and mean glomerular effective filtration pressure was 12...

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...

The flow of gas in the suction chamber of an air brake compressor was analyzed, and losses due to pressure drop and heat transfer were identified by CFD simulations. Based on the results of the calculations the geometry of the suction chamber was modified to investigate possible improvements. Due to simple design modifications the flow direction of the gas was changed, which resulted in a reduc...

To improve the combustion and emission characteristics of diesel engines, methanol-diesel fuels with different mixing ratios (DM0, DM10, DM20, DM30, DM40) were used to investigate effects methanol addition on a four-stroke engine in terms cylinder pressure, brake power, brake-specific fuel consumption, nitrogen oxides, soot, carbon monoxide emissions. Firstly, an improved entire model was devel...

The most important machine elements of the braking system are brake disc and pads. During process, torque is necessary to decelerate speed vehicle or stop it. High amount frictional heat will be generated during process due sliding between moving part (brake disc) fixed parts pads). present research involves two parts, in first it investigated effects difeeerent properties three friction materi...
