The article proposes a dynamic for design (DFD) procedure for a novel aperture grating
tiling device using the multibody system (MBS) approach. The grating device is considered as a rigidflexible
MBS that is built primarily based totally at the load assumptions because of grating movement.
This movement is utilized in many industrial applications, such as the compression of the laser pulse,
precision measuring instruments, and optical communication. A new design procedure of tiling
grating device frame is introduced in order to optimize its design parameters and enhance the system
stability. The dynamic loads are estimated based on the Lagrange multipliers that are obtained from
the solution of the MBS model. This model is fully non-linear and moves in the three-dimensional
space, and the relative movement of its bodies is restricted by the description of the constraints
function in the motion manifold. The mechanism of the grating device is structurally analyzed
in keeping with the dynamic conduct and therefore the generated forces. The symbolic manipulation
as well as the computational work of solving the obtained differential-algebraic equations (DAEs)
is carried out using MATLAB Symbolic Toolbox. Once the preliminary design has been attained,
the stress behavior of the grating device is examined using theMATLAB FEATool Multiphysics toolkit,
regarding system stability and design aspects. Moreover, the design was constructed in real life , and
the movement has been verified experimentally, which confirms the effectiveness of the proposed
procedure. In conclusion, the DFD procedure with trade-off optimization is utilized successfully to
design the grating unit for maximum ranges of grating movements. |
