Abstract： Aiming that the modeling of planetary gear is complicated in mechanical applications，using the secondary development tools-the APDL language in ANSYS，combined with Visual Basic，parameterized analysis of the planetary gear was presented. Via the READ INPUT LOG FROM command in ANSYS input command stream files，modeling，meshing，executive solving，then displays solution results by ANIMATE，PLOT command，the dynamic model simulation was achieved，and the natural frequency and the vibration mode was obtained. Finally，the ANSYS's user interface was designed by VB. The results indicate that the research accomplishes the parametric design about model analysis of planetary gear based on ANSYS.
