Seven factors were considered. The analyses show that the most important factor for the first eigenfrequency is stiffness of the support systems, and the main factor resulting in the relatively low first eigenfrequency of the MGA is its weak support systems. From the OADs optimization analysis, mechanical design of the MGA was improved, and its dynamic performance was improved obviously.
