Description

technical field [0001] The invention relates to a calibration device, in particular to a structure strength simulation parameter verification calibration device and method. Background technique [0002] In the structural simulation work, it is necessary to input the material properties of all parts, such as density, elastic modulus, Poisson's ratio, yield limit, fracture strength, etc. These properties of commonly used materials are generally obtained according to tensile experiments, which belong to the inherent properties of materials. However, in actual production, affected by factors such as material composition, process parameters, preparation methods, and impurities, even for the same material, there will be gaps in the inherent properties of different batches of materials from different manufacturers. When we do simulations, we often ignore this gap. When setting simulation parameters, we always set them according to the inherent properties of materials, so the simul...

Problems solved by technology

However, in actual production, affected by factors such as material composition, process parameters, preparation methods, and impurities, even for the same material, there will be gaps in the inherent properties of different batches of materials from different manufacturers.

When we do simulation, we often ignore this gap. When setting the simulation parameters, we set them according to the inherent properties of the material. The simulation results produced by this method have a large deviation.
