Development of virtual experimental environment for worm-gear drive based on Unigraphics software (UG)

In consideration of the complexity of experiment on worm-gear drive, the advanced Unigraphics CAD/CAE software is used to establish a virtual experimental environment of worm-gear drive. Based on the effect of each factor on the worm-gear drive, a database for each influencing factor is established and is linked with UG, the parametrizational design function driven by knowledge is used to establish a 3D model of worm wheel and worm gear by using the parameters in program calling database, the arrangement of each parameter is made for establishing the virtual environment for worm-gear drive, and the environment is used to conduct a test on the actual worm-gear drive. The result shows that the virtual environment can basically meet the test requirements and reliable calculating basis can be provided for design of the worm-gear drive by using the test data, and a lot of test times and cost can be saved.
