Temat postu: abercrombie uk Radar antenna axis dynamic response
Radar antenna axis dynamic response of mechanical systems
By 25m / s the role of uniform wind speed (wind direction change), is calculated to maintain uniform rotation per minute for 6 weeks required for the antenna array of driving torque and the displacement of the surface point A (given in the form of curves) taking into account the stiffness of a better antenna base and minimize the computation, one revolution of the antenna is divided into 50 intervals, the total number of 575 nodes, plates, a total of 1088 beam elements. Calculated using the above method 2O seconds before the results will be converted to the displacement A coordinate system, and then calculating the data plotted curve shown in Figure 3,

, Figure 4 (Figure 3 is a magnification of 500 times the deformation after the superposition of rigid body displacement result, because A point of rotation radius 3.5m, elastic deformation (mm level) is too small compared with the rigid displacement, Figure 4 is also the speed, acceleration amplitude 500 times put too much on behalf of equation (7) after the drawn curve). Enormous amount of computation in this case, the Pentium 100 with dozens of hours of operation. Figure 2 diagrams a certain type of antenna selection Lei Li Pu, etc. Phase 1: Single radar antenna mechanical system dynamic response 1O5l / B 3-point displacement curve of Figure 4, torque curve results obtained by the appropriate pre-antenna (1 soft body), Antenna (0 soft body) of the modal matrix (just take the first few vibration modes), then the modal coordinates, the order of differential equations can be greatly reduced, greatly improving efficiency, but for the rotation of the antenna ,
