The equation that the block uses to calculate brake torque, depends on the wheel speed. The disc brake is a wheel brake which slows rotation of the wheel by the friction caused by pushing brake pads against a brake disc with a set of calipers. Remember on an opposed piston disc brake its only the area on one side of the disc. Cross drilledventilated, 320mm, 80mm bolt spacing, 5 bolt pattern. For analysis ventilated disc brake was messed using triangular surface mesher. The grabcad library offers millions of free cad designs, cad files, and 3d models. Brake design calculations by engineeringclicks on 2nd november 2011 brakes are machine elements that absorb kinetic or potential energy in the processes of slowing down or stopping a moving part. Motorcycle uses the hydraulically operated foot brakes on the rear wheel. This page contains disc brake seminar and ppt with pdf report. Join the grabcad community today to gain access and download. The operating temperature of the brake disc is controlled, to avoid brake fade and reduced performance the basic data needed to make an initial calculation are any outofbalance forces acting on the machine, and the total inertia of the moving parts of the machine. The disc brake applies the force at the brake pad mean radius. The disc carrier has been optimized for force transfer, and as such is oneway.
Disk and shoe brake equations and calculators stopping capacity is proportional to the normal force of brake shoe against the drum and coefficient of friction. Disk brake design equations and calculator engineers edge. Pdf fatigue life assessment for brake disc of railway. Engineering inspiration brake system design calculations. Disc brakes are a brake system that slowly a wheels rotation by force an attached element disk in a viselike hydraulic caliper. A measure of sensitivity is the amount the brake factor varies for a change in lining friction. The brake disc or rotor in american english is usually made of cast iron, but may in some cases be made of composites such as reinforced carboncarbon or ceramic matrix composites. So, the model is meshed and then analysed to get the detail and correct result of the stress of the contact surface figure 5 thermal meshing of disc brake figure 6 structural meshing of disc brake.
Pressure is a function of the required clamp load and the piston area. Brake caliper is the end part of effort transmission in brakes which retards the motion of two wheeler 3. A disc brake converts brake cylinder pressure from the brake cylinder into force. A layout of the proposed braking system is shown in figure 4. Hose is for transmission of oil from master cylinder to brake caliper 4. Disc brake seminar ppt with pdf report study mafia. Disk and shoe brake equations and calculators engineers. The number of nodes used in this meshing is 43161 and elements are 28042. The piston in turn squeezes two brake pads against the disc rotor, which is attached to wheel, forcing it to slow down or stop. Design and analysis of disc brake rotor for a two wheeler.
