Abstract

Based on the theory of plate and shell, the rationality of shell element in building thin-walled structure is proved by the method of model comparison and test verification, and the general method of model verification is put forward. First of all, a series of gearbox models with different thickness diameter ratio γ are established for calculation and comparison. The results show that the shell element can better simulate the gearbox structure in the range of 0.014 < γ < 0.037. According to this, the shell element is used in ANSYS to establish the simulation gearbox model for modal analysis. In order to further verify the reliability of the model, the modal test is carried out for the simulation gearbox. The test results are in good agreement with the finite element analysis results by verifying the natural frequency and the modal mode confidence.
