For quality assurance and technical refinement of brakes, which are of course highly important for vehicle safety, the brake R&D engineering community makes extensive use of a variety of dedicated brake test systems. For example, a friction tester can evaluate wear-behaviour and friction coefficient of materials and is utilized for managing the production quality of such materials. An inertia type brake dynamometer is the defacto test machine used for doing fundamental R&D work on friction material and brake assemblies. A brake NVH dynamometer is a helpful tool for testing the noise, vibration and harshness (NVH) generated by brakes. For the inertia type brake NVH dynamometer, complete brake assemblies along with relevant suspension system and complete axle structure are subject to NVH measurements. On the chassis type brake NVH dynamometer, the complete vehicle in its original condition is used as the test specimen.
A reliable brake is the most fundamental safety system of all vehicles. Even 2000 years ago Roman soldiers' chariots had a block brake incorporated. In order to manage the complex challenge of quality assurance and further technical refinement of vehicle brakes, the worldwide brake R&D engineering community makes extensive use of a variety of dedicated brake test systems. The most common brake test machines, used for investigating the basic brake's performance, power, wear, durability and NVH-behaviour are listed in Table 1. In this article, we introduce the brake test systems provided by HORIBA.
