Patent ID: 6873925

Claim:
A method of calculating the forces (F xw , F yw , F zw ,) applied at an interface (Q) between a revolving element ( 1 ) and a support ( 2 ) on which said element revolves about an axis Y, said element being associated with a rotating race of a bearing so as to revolve jointly therewith, said method using a set of fixed sensors capable of delivering three independent signals (S 1 , S 2 , S 3 ) representative of the forces being applied on the fixed race of the bearing and which result from the forces (F xw , F yw , F zw ), said method comprising: an iterative processing procedure providing the following steps: acquisition of the signals (S 1 , S 2 , S 3 ); solving of the system (S) S i =(A i ×F xw )+(B i ×F yw )+(C i ×F zw )+K i with I=1 to 3 so as to obtain the values of the forces F xw , F yw and F zw ) corresponding to each acquisition; and a calibration procedure which is carried out before the first iteration of the processing procedure and which provides the following steps: determination of the constants K i ; application at a given interface (Q 1 ) of successively three given forces (F 1 , F 2 , F 3 ), so as to determine, by acquisition of the signals (S i ) and solving of the corresponding systems (S), parameters A i , B i , and C i .
