The length of the braking test track at the Aldenhoven Testing Center is 150 m, which contains an asphalt and a ceramic pavement lane. Both lanes are 4 m wide and may be wetted as preferred. The braking test lane is surrounded on both sides by a safety zone. A 200 m access acceleration lane is also part of the braking test track. [3]
A roller brake tester is a method of allowing the dynamic assessment of the braking system of a motor vehicle, whilst the vehicle itself is in a static condition.This type of brake tester is normally used in UK garages when used as part of an inspection lane for the MOT test.
Cold Performance Equivalence and Speed Sensitivity Tests For the tests the vehicle brake for which the replacement linings are designed is installed in an inertia dynamometer instrumented for continuous recording of rotative speed, brake torque, brake line pressure, number of rotations after brake application, braking time, and brake rotor ...
Random vibration testing is one of the more common types of vibration testing services performed by vibration test labs. Some of the more common random vibration test standards are MIL-STD-810, RTCA DO-160, and IEC 60068-2-64.
Use of the vibration-fatigue methods is well-suited, as structural analysis is studied in the frequency-domain. Common practice in the automotive industry is the use of accelerated vibration tests. During the test, a part or a product is exposed to vibration, that are in correlation with those expected during the service-life of the product. To ...
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
The type of brake system in use only affects trucks and large mass vehicles, which cannot supply enough force to match the static frictional force. [1] [Note 2] The braking distance is one of two principal components of the total stopping distance. The other component is the reaction distance, which is the product of the speed and the ...
