Abstract

The invention discloses an impact load simulation system for a drop-type impact test, relates to the technical field of computer aided design and device drop-type impact tests, and aims at solving theproblems of high cost and poor accuracy of drop-type impact test simulation in the prior art. Model verification is carried out on an established simulation model. A certain simulation method is adopted to perform numerical expression on an input load of the impact machine, the impact load and a simulation model are subjected to impact response calculation together and are compared with a test result, and the simulation model is corrected to correspond to the test result, so that impact resistance response calculation is performed in a design stage, and the calculation accuracy is improved; the basis is provided for impact resistance design of the gear box to satisfy design economy requirements of the gear box, simulation is carried out, the cost is low, the accuracy is high, and accuracyis improved by more than one time compared with a general simulation method.

Description

technical field [0001] The invention relates to the technical field of computer aided design and device drop impact test, in particular to a drop impact test impact load simulation system.
