Brake Pads Dynanometer Test Machine

Core Functions & Inertia Simulation Principle

This dynamometer test machine integrates mechanical inertia and electrical inertia to perform brake performance tests and NVH tests on assembled brake systems, with the capability to replicate braking performance for a broad range of vehicle sizes.
Key inertia simulation features include:
  • Precise vehicle inertia point testing via the drive motor system, which adjusts energy by adding or subtracting from the rotating system.
  • FU CHUN JIANG Intelligent Brake Pads Machines optimizes this inertia simulation to balance test authenticity and operational flexibility, catering to diverse vehicle braking test scenarios.

Advantages of Inertia Simulation Dynamometer

The inertia simulation-equipped dynamometer offers distinct operational and cost benefits:
  • Lower upfront costs due to reduced mechanical inertia discs, and shorter downtime for disc replacement, boosting overall test efficiency.
  • Enhanced flexibility to adjust inertia values during testing, and higher accuracy by eliminating machine operation losses.
  • This advantage set aligns with the reliable performance standards of FU CHUN JIANG Intelligent Brake Pads Machines.
