A continuous flow, liquid helium cooled vibration cryostat with a useful cold space of 200 mm diameter and 160 mm height is described. The cryostat (weight 9 kg) is attached to the armature of a vibration magnet. Cool-down to 4.2 K takes ~ 15 rain and warm-up 1 h. The vacuum jacket and radiation shi

An iterative method, called effective independence, is used to place a small number of sensors on a large space structure for identification of a set of dynamically important mode shapes. The work is important in the area of on-orbit modal identification where a very limited number of sensors will b

For a Timoshenko beam model the equations of motion, representing the anisotropic continuum model of a two-dimensional, latticed, large space structure, are extended to include coupling between the extensional, shear and bending modes. This analytical model, applied to a 20-bay, orthogonal, tetrahed
