Claim 4:
5. The evaluation method according to claim 4, wherein a calculation formula of the comprehensive evaluation value of the health state of the component to be tested is:

H=(R*WR+U*WU+M*WM)*CR*CU*CM,  formula (5)

wherein H is the comprehensive evaluation value of the health state of the component to be tested,
R is an evaluation value of the health state of the component to be tested in the operating data dimension and is obtained according to the formula (1),
U is an evaluation value of the health state of the component to be tested in the environmental data dimension and is obtained according to the formula (1),
M is an evaluation value of the health state of the component to be tested in the maintenance data dimension and is obtained according to the formula (1),
WR is a weight coefficient of the operating data dimension,
WU is a weight coefficient of the environmental data dimension, and
WM is a weight coefficient of the maintenance data dimension,
wherein WR+WU+WM=1,
CR is a fault coefficient of the operating data dimension,
CU is a fault coefficient of the environmental data dimension,
CM is a fault coefficient of the maintenance data dimension, and
values of CR, CU, and CW are 0 or 1.
