Large components, such as base structures and head stock, now form the foundation of high-speed test beds. In addition to the FEM simulations to determine the stiffness, the correct manufacturing process and the validation of the required properties are decisive here to be able to guarantee all the functions of machine frames.<\/p>\n

Over the years, ERNST has acquired core competence in the design and manufacture of machine frames for test bed design.<\/p>\n<\/div>\n<\/div>\n

\n
\n

In this regard, ERNST is able to offer the entire development cycle, from the concept to the fully assembled base frame.<\/p>\n

In addition to the classic base frames of\u00a0E motor testing, these also include solid components such as head stocks, which are used in combination with span fields.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
