Multi-leaf steel plate spring model generation system and method

Abstract

The invention belongs to the technical field of automobile parts, and discloses a multi-leaf steel plate spring model generation system and method. The method comprises the steps that a parameter acquisition module acquires target parameters of a target multi-leaf steel plate spring model; the first parameter updating module updates a corresponding first target candidate value according to the target parameter; a constraint relation determination module searches a constraint relation corresponding to the first target candidate value and the target parameter in a preset constraint relation library; a second parameter updating module updates a corresponding second target candidate value according to the target parameter, the first target candidate value and the constraint relation; and the model generation module generates a target multi-leaf steel plate spring model based on a preset point line selection rule according to the target parameter, the first target candidate value and the second target candidate value. Through the mode, the target parameters can be obtained as required, and meanwhile, the theoretical relationship among the parameters can be automatically updated, so the multi-leaf steel plate spring model can be quickly generated in a manner of being closer to a real form.

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.
