The embodiment of the invention provides a rail train body strength simulation and test benchmarking method and device. The method comprises the steps: determining the position and direction corresponding to a measurement point according to the first principal stress distribution in a train body strength simulation calculation result; according to the position and the direction corresponding to the measuring point, determining the position and the direction to which a strain gauge used by the solid model in the test is attached, and setting the strain gauge according to the position and the direction to which the strain gauge is attached; performing a preset number of tests on the solid model to obtain a vehicle body strength test result; and performing benchmarking on the vehicle body strength simulation calculation result and the vehicle body strength test result. According to the embodiment of the invention, the simulation test benchmarking process is more standard by stipulating the simulation test benchmarking work process; compared with multiple benchmarking in the prior art, only one-time benchmarking is needed, the processing time of test and simulation data is saved, manual intervention is not needed, the data error rate is reduced, and the benchmarking efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of rail train car body strength simulation and testing, in particular to a rail train car body strength simulation and test benchmarking method and device. Background technique [0002] Both simulation and test are important means of product verification. The test can not only verify the actual processed car body model, but also check whether the structural strength of the car body meets the requirements. On the one hand, simulation can be used to verify the design scheme in the design stage, and on the other hand, it can predict the location of structural dangers and provide reference for the arrangement of test measuring points. At the same time, it can also supplement the insufficiency of test data and obtain more comprehensive structural strength data. However, if the error of the simulation model is large, the risk of the structural strength of the car body cannot be well predicted, and the calculation...
