Multi-leaf spring model generation system and method

Abstract

The invention belongs to the technical field of auto parts, and discloses a multi-leaf leaf spring model generation system and method. The method includes: the parameter acquisition module acquires the target parameters of the target multi-leaf leaf spring model; the first parameter update module updates the corresponding first target candidate value according to the target parameters; the constraint relationship determination module searches for the first target in the preset constraint relationship library The constraint relationship corresponding to the candidate value and the target parameter; the second parameter updating module updates the corresponding second target candidate value according to the target parameter, the first target candidate value and the constraint relationship; the model generation module updates the corresponding second target candidate value according to the target parameter, the first target candidate value And the second target candidate value is used to generate a target multi-leaf leaf spring model based on a preset point line selection rule. Through the above method, the target parameters can be obtained on demand, and the theoretical relationship among the parameters can be automatically updated at the same time, so that the multi-leaf spring model can be generated quickly and closer to the real shape.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a multi-leaf leaf spring model generation system and method. Background technique [0002] Leaf spring suspension is a suspension structure widely used in the field of commercial vehicles in my country. Most automobile manufacturers will apply CATIA software in design verification. However, CATIA can only simulate the motion process of the rigid body model in the motion mechanism module (DMU). For elastic bodies with multi-state changes such as leaf springs, they cannot be used frequently in the two engineering design checks of CATIA assembly design and DMU. The model generation process of efficient, accurate and close to the real shape is carried out in the module. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art.
