Open service is an important function of the engineering research centers of the Ministry of Education. Mountain Bridge and Materials Engineering Research Center of Ministry of Education has actively responded to national policies and accumulated some experience in open service. Open services mainly include the setting of open funds, hosting academic conferences, opening and sharing instruments and equipment, actively conducting academic exchanges, actively exploring and deepening international cooperation in production, learning and research, as well as conducting international cooperation, scientific communication, and foreign technical services. These innovative measures have greatly stimulated the service ability, research and development ability, social influence and foreign exchange vitality of the center, and explored a new mode for the open service of the engineering research centers of the Ministry of Education of local universities. The achievements of the center in open service can provide reference for the construction and operation of similar engineering centers.
