Disk Brakes

Abstract: The disk brakes are special mechanized parts in a vehicle attached with the tires to help reduce the velocity of the vehicle. As the brake pads caused friction with the disc brakes, there is a temperature rise. Due to this there are great chances of disc brake’s failure if temperature rises above some permissible limit. Solidworks and ANSYS are the design and analysis tools which are used to accomplish this project. The disc brake was designed using Solidworks and it was analysed in ANSYS workbench. The main aim of this project is to analyse two-disc brakes manufactured with different materials to compare their properties and select one with most benefits.

Abstract: Brakes are one of the most significant safety systems in an automobile. In the braking process, the rotor will be exposed to large stresses which result in surface cracking, overheating of brake fluid, seals and other components. Therefore one of the main tasks of the braking system is to reduce the surface temperature of the brake rotor. This can be achieved by choosing the right material which will undergo the least thermal stresses. In this project, thermal analysis for vented disc brake rotor of Mahindra Bolero’s done, for providing an efficient material for disc brake rotor and brake pads which can dissipate heat generated during braking at faster rate and also being structurally safe.

Disc Brakes

The braking system is very important on a motorcycle. The primary function of the braking system is to slow down and even stop the motorcycle. The braking system using disc brakes on motorcycles is commonly used today, especially on automatic transmission motorcycles. One of the disadvantages of disc brakes is the heat caused by the disc's friction with the brake pads if you apply continuous braking. This continuous braking is often done by a motor rider when crossing downhill roads in mountainous areas. Excessive heat in the disc brakes causes the brake fluid to boil, resulting in air bubbles resulting in braking failure. The failure of the braking system on a motorcycle is hazardous for the rider and others. The experimental method detects braking system failure by catching the disc brake's temperature with a touchless temperature sensor, MLX90614. Temperature detection is processed with Arduino as a control, and the temperature is displayed on the LCD. If the disc brake temperature is above 200oC, a buzzer is activated as a warning to the driver. The test results show that the system can display a temperature reading on the LCD lower than the thermometer gun, with the most inferior reading difference of 0.2oC and the highest 0.4oC. The system can also display notifications to users on disc brake temperatures above 200oC, namely at temperatures of 211.1oC, 224.3oC, and 237.5oC, which were achieved at 200, 225, and 250 seconds.

Disc brakes have been applied in various automobiles widely and their braking performance has vitally important effects on the safe operation of automobiles. Although numerous researches have been conducted to find out the influential law and mechanism of working condition parameters like braking pressure, initial braking speed, and interface temperature on braking performance of disc brakes, the influence of magnetic field is seldom taken into consideration. In this paper, based on the novel automotive frictional-magnetic compound disc brake, the influential law of magnetic field on braking performance was investigated deeply. First, braking simulation tests of disc brakes were carried out, and then dynamic variation laws and mechanisms of braking torque and interface temperature were discussed. Furthermore, some parameters including average braking torque, trend coefficient and fluctuation coefficient of braking torque, average temperature, maximum temperature rise, and the time corresponding to the maximum temperature rise were extracted to characterize the braking performance of disc brakes. Finally, the influential law and mechanism of excitation voltage on braking performance were analyzed through braking simulation tests and surface topography analysis of friction material. It is concluded that the performance of frictional-magnetic compound disc brake is prior to common brake. Magnetic field is greatly beneficial for improving the braking performance of frictional-magnetic compound disc brake.

In the present paper, air pressure and temperature on the interface of the polymer matrix composite (PMC) brake pads are measured by disc brake under braking condition, and their influences are studied as well. The experimental results show that the air temperature peak is not as high as that on the surface. The air pressure of the interface varies with the applied load. The air pressure is negative under the small applied load, but positive under the large applied load. The analysis of the experimental results shows that the phenomena are caused by the friction heat and the rotate disc. Since the air pressure is very small comparing with applied load, it influences on the friction coefficient slightly. But, the negative air pressure of the interface increases the chance of the drag friction in the non-braking mode for disc brakes.

High temperatures are one of the main problems encountered in disc brakes, contributing to rapid wear and poor braking performance. In this paper, a two-dimensional finite element model using a thermomechanical algorithm is used to predict the evolution of the bearing surface and temperature distribution at the interface between the disc and pad. After determination of the temperature of a conventional brake configuration, the behaviour of several modified friction pad designs is simulated numerically in order to improve contact and so to achieve lower surface temperatures.

This study aims to determine the effect of brake pads material to the vibration response of disc brake system on many variety of braking conditions. The variations of brake pads material on this research such as metallic, non-asbes and ceramic. The variations of braking operation such as speed of disc rotation and braking pressure. Each brake pads material tested by variation of disc rotation 425, 637, 850, 1062 rpm and pressure variation 0,5 bar, 1 bar, 1,5 bar. Furthermore, the dynamic characteristics of brake pad had been tested by using the method of Modal Analysis Experiment. The results showed that the type of brake pad materials, disc rotation and braking pressure affect to vibration response of disc brake system. Increasing speed of disc rotation and braking pressure will increase the excitation force causing value amplitude of vibration in the braking system increases. Usage of brake pad ceramic also showed the lowest amplitude of vibration for all variations of disc rotation and braking pressure. Because the ceramic brake pad have the lowest natural frequency, then the value of the damping ratio is high, so that decreasing amplitude of vibration that occurs in the braking system.

Braking system is one of the basic organs to control a car. For many years, the disc brakes have been used in automobiles for safe retardation of the vehicles. During braking, enormous amount of heat will be generated, and for effective braking, sufficient heat dissipation is essential. The specific air flow surrounding the brake rotor depends on the thermal performance of the disc brake and hence, the aerodynamics is an important in the region of brake components. A CFD analysis is carried out on the braking system as the study of this case, to make out the behaviour of air flow distribution around the disc brake components using ANSYS CFX software. The main object of this work is to calculate the heat transfer coefficient (h) of the full and ventilated brake discs as a function of time using the CDF analysis which will be used later in the transient thermal analysis of the disc in ANSYS Workbench 11.0.
