Method for calculating bonding area of automobile brake pad lining

Abstract

The invention provides a method for calculating the bonding area of an automobile brake pad lining, and the method comprises the following steps: placing a brake pad and a calibrated scale on a scanner flat plate at the same time, setting the lining of the brake pad to be downward, setting a fixed scanning resolution and a storage format to be in a JPEG format, and carrying out the scanning and filing; opening the picture by using Photoshop CS6 software, and adjusting the picture until the outline is clear; measuring length pixel values B corresponding to the fixed lengths A at different positions on the graduated scale, calculating the value of C'at the position according to the value C '= B / A of the formula scale, and calculating the average value of C' to obtain the value C of the average scale; selecting the outline of the edge of the brake pad lining; and in the histogram of the scanned picture, reading the pixel value of the area of the brake pad lining as D, and calculating thevalue of S by using S = D / C2 according to the formula of the bonding area of the brake pad lining. According to the method, the bonding area of the brake pad lining can be calculated more quickly, more visually and more stably.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a method for calculating the bonding area of ​​an auto brake lining. Background technique [0002] Automobile brake pads, also known as automobile brake pads, refer to the friction material fixed on the brake drum or brake disc that rotates with the wheel. It is generally composed of steel plates, bonded heat insulation layers and friction linings. Anti-rust, SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure the quality during the coating process. Among them, the friction lining is subjected to external pressure and produces friction so as to achieve the purpose of vehicle deceleration. [0003] The brake pads are not attached with their bonding area parameters when they leave the factory, while GB / T 22309-2008 "Test method for shear strength of brake lining disc brake assembly and drum brake shoe assembly of roa...

Problems solved by technology

[0004] Technical problem to be solved: Aiming at the disadvantage that the existing brake pads do not have their bonding area parameters when they leave the factory, the present invention provides a method for calculating the bonding area of ​​automobile brake pad linings, and the brake pads to be calculated are obtained by scanning with a scanner. Use Photoshop to process the projected image of the film, check the outline of the bonding area of ​​the brake pad lining, and calculate the bonding area of ​​the brake pad lining from the pixel value of the selected area through the scale
