Problems solved by technology

[0005] 1. In the process of manually correcting the model, it is necessary to continuously adjust the relevant parameters repeatedly, which not only has a large workload, but also brings a lot of repetitive calculation work to the simulation engineer in this process
[0006] 2. In the process of correcting the model above, the engineer needs to combine his own engineering experience to correct the simulation parameters. Therefore, there are high requirements for the simulation experience and engineering experience of the engineer, and the influence of human factors is difficult to eliminate.

Abstract

The invention discloses a verification tool for a static model, and relates to the technical field of computer simulation. A simulated analysis process template can be customized according to the simulated analysis requirement for structural mechanics calculation, and knowledge and experience obtained through simulation model verification are cured inside the template to be provided for differentworkers for use, so that the calculation result consistency of different workers is effectively improved. The customized simulation analysis template can be repeatedly called and used for rapid performance evaluation of a model product, precise control is performed through various errors in the simulation process, parameter sensitivity analysis is performed for correcting the numerical simulationmodel, and the model testing efficiency is improved while the problem that simulation precision and credibility are low are solved.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a verification tool for a static model. Background technique [0002] The simulation system is a system that uses a simulation model to replace the researched object in a computer or an environment composed of simulation equipment. With the continuous development of simulation technology and the continuous expansion of the scope of simulation applications, the accuracy and reliability of simulation are becoming more and more important. [0003] In recent years, with the development of simulation technology, many units have gradually begun to carry out research work on modeling and simulation verification and confirmation. In the process of confidence evaluation, in addition to evaluating the confidence of the overall model, the characteristics of each subsystem can also be evaluated, providing a scientific evaluation basis for evaluating the functions and performance...
