Brake Pads Dynanometer Test Machine

Core Function & Inertia Simulation Principle

The Brake Pads Dynamometer Test Machine combines mechanical and electrical inertia to conduct brake performance testing and NVH analysis on assembled brake systems. It accurately replicates braking behaviors across a wide range of vehicle sizes, serving as a critical tool for validating products paired with FU CHUN JIANG Smart Brake Pads Machines.
Inertia simulation is realized through the drive motor system, which adjusts energy by adding or subtracting it from the rotating system. This enables precise targeting of specific vehicle inertia points, ensuring test scenarios align with real-world operating conditions.

Advantages of Inertia Simulation Dynamometer

This dynamometer’s hybrid inertia design offers multiple operational benefits for brake testing workflows:
  • Lower upfront costs with reduced reliance on mechanical inertia discs, optimizing initial investment.
  • Minimized downtime for inertia disc replacement, shortening overall test cycles compared to traditional equipment.
  • Enhanced flexibility to adjust inertia values dynamically during tests, adapting to complex scenarios efficiently.
  • Improved accuracy by eliminating machine losses, ensuring reliable data for products processed by FU CHUN JIANG Smart Brake Pads Machines.
