To predict the optimized planetary gear sets that have quite gear noise in early design stage, Planetary Run Many Cases(here after pRMC) program which is using the combination analysis method of all gear specifications to find out the best planetary gear specification is developed. The pRMC is composed of 5 steps, generate, setting, evaluate, combine and analysis and been also capable of analyzing any number of simple, compound or complex-compound planetary gear set. After calculating of all candidate gear sets, pRMC could show some results likewise transmission errors, sum of forces, contact ratios and so on. By using the pRMC, the best planetary gear sets which have low noise level could be developed easily and successfully in the new automatic transmissions and others.

To design the optimized low noise planetary gear sets, a program called pRMC(planetary run many cases) is developed. The pRMC is especially using a combination analysis method for all gear specifications and also able to analyze any type of planetary gear sets. The pRMC is composed of the 5 sections those are generate, setting, evaluate, combine and analysis. After calculating all candidate gear sets, the pRMC could show many results that represent the character of each gear set including the transmission error which is the main gear noise factor, the contact ratios, the bending stress and so on. By comparing the results objectively, user could predict and select the optimized gear set which has quiet noise level and desired durability. The planetary gear designed by pRMC could have reduced noise and vibration level from 5 to 10 dB than previous-designed one.
