A method for calculating the deflection of a round flat steel plate bearing an ax isymmetric load is considered. For practical calculations, dimensionless coefficients of deflection in the center of the plate, deflection at a certain distance from the center of the plate, the stress coefficient and the accompanying function, which depends on the deflection of the plate and the pressure force on it, are used.

The work presents the equations of the theory of symmetrical plates, resting on one-way, single-layer, two-parameter Vlasov’s subsoil. Two cases of differential equation solution of the plate deflection of thin and medium thickness on the ground substrate were analyzed depending on the size of the integral characteristics UÖD and 6ÖD. The example of loading the circular plate with a Pk load evenly distributed over the edge was considered and shows dimensionless graphs of deflection, bending torques and transverse forces in the plate and in the ground subsoil. The effect of the Poisson’s coefficient of the plate on deflection values and cross-sectional forces was investigated. The Poisson’s number has been shown to have a significant influence on deflection values and bending torque, however shown negligible effect on transverse forces values.

The design and analysis of an integration plate for Laser Based Range Finding System (LBRFS) is based on three subsystems which are going to be (payload) mounted on different locations. FEM modeling and simulation of three different configurations have been considered for integration plate in assembled payload conditions. Structural analysis of the plate under the simulated boundary conditions was carried out. Plate deflection at critical point was worked out. Depending upon the results obtained optimum plate thickness with stiffeners at the various locations was incorporated on the integration plate to meet the system requirements.

A solid circular plate unilaterally supported along two antipodal edge arcs and deflected by a static central transverse concentrated force is considered. It is clarified that two distinct mechanical responses are possible, depending on the angular extent of the supports; in the first kind of response, valid for small support angular widths, the plate rotates about the support lateral sides, lifting from the supports along their central zone. The second response is valid for high support angular extents, and according to this response the plate additionally beds over the central portion of the support upper faces. Only the first kind of response is examined in this paper. This plate contact problem is classifiable as receding, and the plate deflection is described in terms of a plate Kirchhoff model. The plate deflection is analytically expressed together with the transitional value of the support angular width that describes the passage from the first to the second mechanical response.
