The invention provides a turbine blade margin plate damper optimization design method. The turbine blade margin plate damper optimization design method comprises the steps that design constraint conditions of a margin plate damper are determined; forming a preliminary structure scheme of the margin plate damper based on the design constraint conditions, and obtaining characteristic parameters and size parameters of a margin plate damping structure; statics analysis of the turbine blade in a typical working state is carried out based on the preliminary structure scheme; the vibration response of the turbine blade and a margin plate damper is solved based on the turbine blade characteristic parameters and the equivalent damping stiffness; carrying out a static damping effect test on the turbine blade and the margin plate damper; and carrying out a rotation excitation damping effect test which is the same as the real working state of the turbine blade, verifying whether the vibration reduction effect of the marg
