Abstract

The invention relates to a method for optimizing an automobile product development system based on hierarchical decomposition. The method comprises: determining an optimized product development target; transmitting the development target in the entire vehicle hierarchy to lower hierarchies, namely the system hierarchy and the component hierarchy; realizing synergistic optimized solving among various hierarchies; and realizing the flexibility of a development task and modularized execution of development subtasks by combing the method with a multidisciplinary design optimization method. The invention provides the method which has quick convergence speed and high solving quality and can simultaneously realize optimization of development performance indexes and a design proposal in the entire vehicle hierarchy, the system hierarchy and the component hierarchy.

Description

technical field [0001] The invention relates to a method for optimizing an automobile product development system based on hierarchical decomposition, which is a method capable of simultaneously realizing the optimization of development performance indicators and design schemes at the vehicle level, subsystem level and parts level. Background technique [0002] Product design and development is a series of decision-making processes: determine the appropriate value (type and magnitude) for design variables (component type and size) in order to achieve the optimal design goal (maximize the comprehensive benefits of the overall system performance). [0003] Automotive product development involves safety, energy saving, environmental protection, comfort, as well as requirements for manufacturing and use. Automotive product design involves multiple disciplines such as mechanics, fluids, power electronics, and economics, and requires professionals from multiple disciplines to work ...
