Abstract: In response to the new requirements of the Euro Ⅶ Emission Standard for brake wear particulate matter emissions, the limit values, testing methods, and testing equipment requirements of the Euro Ⅶ Emission Standard for brake wear particulate matter are deeply interpreted, a brake inertia test bench for the Euro Ⅶ emission standard is designed. The bench integrates particulate matter measurement, automatic control system, and mechanical electric inertia hybrid simulation technology, and proposes an overall laboratory layout that is suitable for different site conditions. The practical application results show that the inertia brake platform can accurately measure the number of solid particles, total particle number PM_2.5、PM₁₀. This design scheme not only meets the requirements of Euro Ⅶ Emission Standard, but also improves the accuracy of testing, reduces costs, and optimizes space.
