Where, ( i=1,2,3) and ( j=1,2) mean the torsion angles of clasp arm and stretching arm of the rescue system, and (i=1,2,3) and (j=1,2) mean the common perpendiculars, ( i=1,2,3) and (j=1,2)are the rods’ space-between, and the ( i=1,2,3) and (j=1,2) are rotation angles of the rescue system.
According to Fig.4 and table 1 and 2, we can obtain the matrices Ai(i=1,2,3) and A′j(j=1,2) of the system, just shown as formula (1) and (2) [7]
(1) (2) where i = 1,2,3 and j = 1,2, so we get the following forward kinematical matrices of the clasp arm

Let be a 1 × (n − 1) matrix defined by which is a submatrix of the matrix C in (3).
Choose any (n − 1) × 1 matrix (8) which is a submatrix of the matrix L in (10) and is Hurwitz, which is possible since is observable; see [9] for definition of observability.
Then, there are two (n – 1) × (n – 1) symmetric positive definite matrices and such that (9) Let be an n × n block-diagonal matrix defined by where is to be determined.

FE modeling of the wind turbine yaw bearing A single-row four contact-point ball bearing is used in a 3MW wind turbine to connect bedframe with tower top as illustrated in Fig. 1.
The frame of the yaw bearing is shown in Fig. 2. and main parameters are listed in Table 1.
The maximum von Mises stress in Inner ring is 479.87MPa, and the maximum von Mises stress in Outer ring is 413.87MPa.
