WebJul 25, 2014 · There are 4 key work flow steps: 1. Carry out a modal analysis (guess the number of modes, start with 10,say) 2. Using the results from the modal analysis output (1. above), 'identify' the structure using a 'dynamic shock' analysis.
WebShock is a vector that has units of an acceleration (rate of change of velocity). The unit g (or g) represents multiples of the acceleration of gravity and is conventionally used. A shock pulse can be characterised by its peak acceleration, the duration, and the shape of the shock pulse (half sine, triangular, trapezoidal, etc.). hot city automotiveWebIn order to perform tests for single shock impact, one should set the shape (half-sine, trapezoidal or saw-tooth), amplitude and duration of the pulse. Velocity change should be within the limit of 15% of the nominal pulse. Tests for multiple shocks impact are performed by means of half-sine pulses having certain amplitude, duration, and frequency. pt ortho gardendaleWebThe procedure to calculate the elastic medium to generate any half-sine pulse is first to determine from the time duration of the pulse the frequency (1/2T = f) of the pulse, where. T = time duration, seconds. f = frequency, Hz. Next, one must determine the static deflection of the elastic medium from the formula.
