Abstract:

A brake pad wear control algorithm used under uncritical braking conditions is proposed to reduce the difference in brake pad wear between the front and rear axles caused by the difference in braking force and the type of brake. The algorithm regulates the distribution of braking force within the limits of certain braking regulations according to the wear conditions of the brake pads while deceleration control still functions properly. Computer co-simulations of braking with Trucksim and Matlab/Simulink was performed in which vehicle models with equal brake pad wear, greater wear on the front

This article presents the results of tests conducted on the average and instantaneous friction coefficients of railway vehicle disc brakes. The tests were carried out independently of various states of wear on the friction linings and the brake disc. The requirements of the International Union of Railways (UIC) regarding the approval of brake linings for use were taken into account. Based on many years of research using a brake bench to test railway disc brakes, the authors developed multiple regression models for the average friction coefficient and fluctuations (tolerances) in the instantane

Non-exhaust emissions from brakes and tyres are becoming the major transport-related contributor of particulate matter (PM) pollution in cities. Furthermore, tyre microplastics are the major contributor of unintentionally released microplastics in all environmental compartments.

Abstract:

Brake pad components are important in two-wheeled vehicles because they concern the driver's and others' safety. Brake lining wear is an unavoidable phenomenon. This is because of the concept of braking, which involves bringing two things into contact with each other such that they press against each other and rub against each other. Brake pads that have not been replaced make the brakes unable to work normally, so the potential for accidents is even greater. One of the factors causing the problem is negligence and ignorance of the condition of the ream linings, which should be time for the ch

Abstract:

The wear of brake pads exposed to silica dust was measured. A novel test stand was developed to analysebrake pads' wear exposed to silica dust. Brake pad wear was determined by measuring pad lining geometryand mass changes. Geometric wear was analysed by determining changes in the thickness of the brake padlining during friction tests. In order to determine changes in mass, the brake pads were weighed before andafter the test. Brake pad wear was evaluated under dust-free conditions and under exposure to silica dust. Thetests revealed significant differences in brake pad wear under dust-free co

The wear phenomenon of the braking surface of a high-power disc brake under emergency braking conditions is analyzed in this paper. Considering the classical Archard wear model, including the influence of the braking load, speed, and friction coefficient on the braking surface, the wear model of the brake disc surface is established to obtain the wear depth and distribution. It is essential to investigate the wear mechanism of the brake disc surface, and the evolution of wear laws is revealed under different braking parameters. The results have shown that the brake disc surface wear is constan

Abstract The brake is the key equipment to ensure the safe operation of the elevator. Failure of the elevator brake will lead to a slide accident. This paper takes the elevator brake shoe, which has been used for more than 15 years, as the research object, and systematically analyzes its wear characteristics. The research results show that most of the brake shoes have obvious scratches, and some of them even have cracks. Therefore, in the daily maintenance of the elevator, pay special attention to the wear state of the brake shoe to ensure the safe operation of the elevator brake.

Abstract:

The hard particles in the copper-based powder metallurgic material of a brake pad for a wind turbine brake falls off and presses into the surface of the brake disc to form abrasive particles under high-speed and heavy-load working conditions. The presence of abrasive particles will produce abrasive wear with micro-scratch and micro-scribe on the copper-based material of the brake pad. The critical scratch depth effect in the abrasive wear process is proposed based on the critical depth effect of the metal removal process at the micro-scale. The abrasive wear is divided into two types: scratch

As the core component of the automobile braking system, brake pads have a complex structure and high failure rate. Their accurate and effective state monitoring can help to evaluate the safety performance of brake pads and avoid accidents caused by brake failure. The wear process of automobile brake pads is a gradual, nonlinear, and non-stationary time-varying system, and it is difficult to extract its features. Therefore, this paper proposes a CNN-LSTM brake pad wear state monitoring method. This method uses a Convolutional Neural Network (CNN) to complete the deep mining of brake pad wear ch
