Vibration Mode of Gearbox in Test Bed of Gear with Intersecting Axis

A test bed of closed-end mechanical beveloid gear with intersecting axes is designed to measure various parameters. In order to analyze the reasonableness of the structural design and test the performance of the test bed, a three-dimensional solid simulation model of the test bed is set up first with virtual simulation technology to analyze motion characteristics of test-bed and modal analysis to analyze the vibration characteristics of the key components. Simulation test obtains the vibration mode of the test gear box and drive gear box, providing a useful result for the optimization of the test bed. This solves some problems such as that a common test bed cannot test gear with intersecting axis and must have the same test pair gear, and inaccuracies of measuring transmission efficiency.
