Abstract: Provided is an ultra-stable multi-directional low-frequency actuator, including a baseplate, a bearing plate, a connecting mechanism, and two executing mechanisms symmetrically arranged on the baseplate about a Y axis. Both ends of a lower part of the support leg are connected with the baseplate through one high-static low-dynamic spring damper and one vertical executer arranged in parallel, respectively. Both ends of an upper part of the support leg are provided with one sensing component, respectively. A horizontal executer and an elastic component are arranged in parallel between each of both sides of a lateral support seat and a first groove, and sensing components corresponding to the horizontal executers one by one are arranged at an inner side of the support leg. The connecting mechanism is configured to connect two support legs, both ends of the bearing plate are mounted at the upper parts of the two support leg.
