Pressure influence on heating of ventilating disc brakes for passenger cars

Abstract

The braking system is one of the most important elements in vehicle systems from the aspect of vehicle safety, besides the steering system and the internal combustion engine. During the braking process, the disc and pads absorb a large amount of kinetic energy that converted to heat. Owing to this frictional heating, it is necessary to compute the temperature distribution that will be appeared during the braking process, which is the main goal of this research paper. There are many factors that can be influenced to the distribution of frictional heat generated. One of the significant factors is the applied pressure by the brake pad on the braking disc. The results proved that when increased the applied pressure then the frictional heat generated increased too. It was developed a new finite element model based on observed data from real vehicle. It was used ANSYS/WORKBENCH 14.5 software to perform the numerical analysis, module Transient Structural. Parts that are the most disposed to the thermal stress are braking pads. Also, it was found time period from 0 to 0.1 second is the most critical period during the whole braking period, because in this period, temperature rises rapidly, the maximum temperature occurred at 1.338 seconds, and after that it falls.

Analysis of the Thermo-Mechanical Behavior of a Multi-Plate Clutch during Transient Operating Conditions Using the FE Method

“…In the literature, thermo-mechanical models of truck and train brakes have been developed more often [11][12][13][14]. In contrast, Zhao et al [15] investigated the thermo-mechanical behavior of a multi-plate dry clutch made of a carbon-carbon composite material.…”

The Influence of the Braking Disc Ribs and Applied Material on the Natural Frequency

“…Where, during the braking process the braking disc is always in contact with braking pads, and there is amount of heat is generated at the interface between the disc brake and braking pads. Because of the material characteristics of these two elements, different amount of heat will penetrate each element [16], this will lead to different temperature distributions on each element. With higher differences of temperature between these two elements, the higher level of noise will appear [17].…”

Quality assessments, performance, and emissions evaluation of biodiesel from citrullus lanatus oil seeds and diesel blends in compression ignition engine

“…The objectives of this research are to compare and evaluate the performance of the biodiesel blends with petro-diesel on a stationary multi-cylinder diesel engine, and carry out exhaust air quality analysis of the combustion products (gases) [17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”
