A kind of light truck frame as an object is researched by means of the finite element method.Fiber-optic smart layer is used to analyze the stress of the frame under bending and twisting working conditions.Distributed fiber Bragg grating sensors network which adopted wavelength division multiplexing is designed.At some key point the stress of frame is researched by wavelength inspection
and finite element static strength analysis is researched based on Patran.It is shown by comparison between calculation and test results that they fit closely.This study result supplies a technical measure and a basis for development
improvement and optimal design of the same type automotive.
