Tracked vehicle integrated optimization design system based on FMI

Abstract

A tracked vehicle integrated optimization design system based on an FMI comprises a tracked vehicle simulation model unit, an FMU model conversion unit, a data interface interaction unit and an optimization design unit. On the basis of realizing integrated integration of a vehicle joint simulation model based on an FMI standard model interface, through adopting a parallel optimization scheme of a multi-field subsystem, nested iteration in the optimization design process of a complex system is eliminated, so that the efficiency and the product quality of the optimization design process of the tracked vehicle system are improved.

Description

technical field [0001] The invention relates to a technology in the field of optimal design of tracked vehicles, in particular to an integrated optimal design system for tracked vehicles based on the FMI (Functional Mock-up Interface) standard model interface. Background technique [0002] Tracked vehicle is a large and complex equipment including multi-domain subsystems. It faces problems such as long iteration cycle, low optimization efficiency and unsatisfactory optimization results in the design optimization process. The above problems are mainly caused by the following two aspects: (1) Tracked vehicles involve many fields such as machinery, hydraulic pressure, control, and electronics, and the simulation models of systems in different fields, such as mechanical structure models, multi-body dynamics models, and control system models etc., need to be built in different simulation tools. In the process of tracked vehicle research and development and optimization design, i...
