Overview

The Heavy-Duty Commercial Vehicle Comprehensive Drum Test Bench (hereinafter referred to as the Drum Test Bench) is a special test platform used to simulate road driving for heavy-duty vehicles and passenger cars. The non-driving wheels and driving wheels operate synchronously at the same speed, supporting working condition simulation and custom working condition testing. It is also dedicated to tests such as road driving simulation, noise and vibration measurement.

This equipment is suitable for drum tests of medium and heavy-duty vehicles and passenger cars with a maximum axle load of 10000kg and a curb weight of 5000-20000kg. The test vehicles can be two-axle, three-axle or four-axle vehicles, with one, two or four driving axles, and the number and position of driving axles can be defined arbitrarily.
