Description
technical field [0001] The invention belongs to the field of damage assessment and measurement, and relates to a deflection measuring device, in particular to a portable and assembleable thin plate structure deformation deflection measuring device. Background technique [0002] Aircraft, ships, vehicles and other devices contain a large number of thin-plate structures. Under the action of damage sources such as explosion shock waves and fragments, the thin-plate structures will deform to a certain extent. The degree of deformation is an important basis for measuring the power of ammunition and the effect of target damage. Scholars at home and abroad have carried out a lot of research on the deformation of thin plates under explosive loads, among which the explosion test is the most common research method. Nurick et al. carried out a series of bare charge explosion tests on thin plates fixed on four sides, and analyzed the effects of charge volume and blast distance on the de...
