Document Type and Number:
WIPO Patent Application WO/2024/078531
Kind Code:
A1
Abstract:
A parameter optimization method for a nonlinear vibration model of a complex device, the method comprises the following steps: 1) constructing various structures of the complex device into a tree structure, so as to form a tree-shaped complex device model subsystem, and carrying out sign convention for dynamic analysis; 2) establishing a complex device dynamic model to obtain dynamic relationships among all parts of the complex device; 3) according to contact and collision conditions in the advancing process of the physical complex device, adding constraint relationships among the parts in s dynamic simulation software; 4) on the basis of the dynamic simulation software, establishing a virtual prototype model of the complex device, and determining a target parameter and an optimization target; 5) simulating vibration characteristics of the complex device for different levels of pavement spectrums and different vehicle speeds; 6) adding a required input point and an output point for the virtual prototype model; 7) on the basis of an optimization algorithm of numerical solution in small sample deep learning, obtaining an optimal parameter.
