It has been commonly used for motion and torque transmission in industry. Because there exit multiple contacts between the cycloidal disc and rollers meshing with the disc, and between disc and pins on the output plate, the theoretical force analysis has to make some assumption about the relations among the contact forces. Usually, it is assumed that the magnitude of the contact force is proportional to the length of moment arm which the moments are taken. This assumption makes the force equations solvable. In this proposal, in addition to the theoretical force analysis, a force analysis process using FEA software will be established. This process containing the module construction, meshing, boundary setting, solution techniques and preprocessing will be established using ANSYS Programming Design Language (APDL) to make the parameters setting more accurately. The results of FEM will be compared with those of theoretical analysis.擺線齒減速器力量分析有限元素APDLcycloidal gear reducerforce analysisfinite element methodAPDL
