Scientists from Moscow Polytechnic University have developed a method for optimizing the front suspension of a wheeled tractor as part of a mainline road train. The development allows engineers to determine component requirements in advance and reduce the time for creating new vehicles.

The author of the development, postgraduate student Mikhail Chetverikov, explained that when driving on uneven roads at high speeds, the level of vibrations increases and ride comfort deteriorates. The proposed method allows varying real suspension parameters and finding effective solutions based on several criteria, including handling and stability.

The method solves the problem where a theoretically calculated suspension does not fit into the constraints of mass production in practice. Chetverikov proposed calculating suspension parameters in conjunction with actually available components. The result is checked on a digital twin of the vehicle before engineers start working with metal. Requirements for parts are formed at early stages, suppliers are involved in advance, and costly rework is minimized.
