Brake pads are an important factor in braking, so it is necessary to study the noise and acoustic characteristics of brake using simulation method obtain sound pressure level results, determine simulation, compare results with experimental testing. The simulated composite lining material uses a composition hazelnut shell, pineapple leaf fiber, aluminum, polyurethane. Researchers used simulation...

Peripheral arterial disease (PAD) produces abnormal gait and disproportionately affects older individuals. The current study investigated PAD gait biomechanics in younger (<65 yr) and older (>/=65 yr) subjects. The study included 61 patients with PAD (31 younger, age: 57.4 +/- 5.3 yr, and 30 older, age: 71.9 +/- 5.2 yr) and 52 nondisabled age-matched control subjects. Patients with PAD were tes...

After the realization that asbestos fiber is harmful to human health, efforts produce organic and environmentally friendly brake pads have increased. In this study, an pad (NUS sample) was produced with addition of 3.5% hazelnut shell powder. Hardness density measurements sample were made. Chase type device used for wear friction tests. The experiments done according SAE J661 standard. average ...

The brake pads made from asbestos are environmentally hazardous due to the friction and abrasion occurring during braking, resulting in release of airborne fibers. These fibers pose various health risks humans contribute environmental pollution. This study aims analyze influence adding clamshell waste material on mechanical properties motorcycle disc pads. research utilized an experimental appr...

A method for ultrasonic measurement of friction material elastic constants was evaluated through a round-robin process. The purpose of the study was two-fold: 1) to formulate and evaluate a standard test method (SAE J2725) for measuring elastic constants using ultrasound and 2) to quantify the measurement variability when the testing method is applied by multiple operators and instrumentation. ...
