    • Abstract
  • Image field rotation can occur during the process of nearinfrared camera vertical imaging in optoelectronic stabilized platform in helicopter. In order to eliminate the image field rotation and satisfy the requirements of carrier aircraft space size, the cantilever structure azimuthgimbal was introduced, and the threedimensional model of the azimuthgimbal was established. In order to analyze the rationality of the cantilever structure, the finite element model was established to carry out its static analysis and modal analysis separately. Results show that in load case of 24.5 kg, the maximum deformation is 0.025 4 mm, which meets the requirements of the pointing error distribution; and the first natural frequency is 42.99Hz, which meets the servo bandwidths requirements.
