| Abstract: | Using finite element analysis software MSC.PATRAN and MSC.NASTRAN, static analysis and modal analysis for case structure of laser strapdown inertial measurement unit are carried out. The quantificationally effect of case thickness and sectional area of reinforcing tendon on case deformation amount, stress distribution and fixed frequency is obtained. This method can be used to structural design of other onboard equipments so as to satisfy the requirements of strength-to-mass ratio. |
