Title:
MULTIDIMENSIONAL EXCITING DEVICE
Document Type and Number:
Japanese Patent JP3665493
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a multidimensional exiting device capable of effectively preventing the generation of a crosstalk without using one such as a hydraulic fluid in a conventional static pressure pad type, and efficiently transmitting an intended directional exciting force with a structure applicable also to an excitation having a large load.
SOLUTION: This multidimensional exciting device comprises a vibrating base, a plurality of exciters for vibrating it, and a plurality of joints provided for every exciter to transmit the exciting force of each exciter to the vibrating base. In this device, a joint 4 is formed of a first member 6 having one end fixed to an exciter 2, a second member 7 having one end fixed to the vibrating base, and a transmitting member 8 interposed between the first member 6 and the second member 7, and the transmitting member 8 has a structure having high rigidity in a specified direction and low rigidity in other directions.
