[Dongli Machinery: Tsinghua University delivers R&D results of electromagnetic active suspension system for automobiles] On September 7th, Dongli Machinery (301298.SZ) announced that Tsinghua University has completed the key technology research and development project of electromagnetic active suspension system for automobiles and delivered design information, technical reports, test data, software and hardware code drawings and other results to the company. The project lasted two and a half years, completing the technical research and development of two solutions and six rounds of actual vehicle testing, achieving system closed-loop testing and verifying the feasibility of the technical solution. This cooperation aims to promote the integration of industry, academia and research and enhance the company's competitiveness. However, the transformation of experimental technology into industrialization still requires engineering debugging. There is a risk that industrialization will not meet expectations. It is not expected to have a significant impact on operating performance in the short term.
