Background. The relevance of the topic is determined by the prevalence of monitoring and control tasks for civil engineering products in order to prevent the occurrence of emergency situations. The goal of the work is to develop and master in mass production of unified rows of multilayer piezo-film ceramic elements based on the piezoelectric effect using slip casting technology for the control system of internal combustion engines. Materials and methods. The work uses slip casting and cold semi-dry pressing technologies. Results. The results of research into the technology for creating multilayer piezo actuators for injectors of internal combustion engines, manufactured using slip casting technology, are presented. The technical characteristics of laboratory samples of multilayer piezo actuators manufactured using semi-dry cold pressing technology are presented. The obtained value of the relative working stroke at a control electrical voltage of 200 V ranged from 0.05 to 0.08 %, and at minus 200 V it ranged from minus 0.06 to minus 0.033 %. Further improvement of the technical characteristics of piezo actuators manufactured using semi-dry cold pressing technology, including an increase in the relative working stroke to 0.13 % at a control electrical voltage of 140 V, is possible by reducing the thickness of the piezo plate blanks from 0.2 to 0.1 mm and changes in the method of their metallization and assembly (gluing). |
