Separation of stages, the separation of the spacecraft from the last stage of the launch vehicle will induce very short duration loads in the internal structure of the spacecraft, the so-called shockloads. The duration of the shockload is, in general, very short with respect to the duration associated with the fundamental natural frequencies of the ...

Shock response spectrum of launch vehicle using LabVIEW
2017 International Conference on Innovations in Information, Embedded and Communication Systems (ICIIECS), 2017The seismic measurement signal plays an important role in observing the launch vehicle. Based on the virtual instrument that can measure the vibration signal introduced by the vibration system. The hardware development system includes the sensor's vibration or shock response, a signal amplifier, and data acquisition and PC devices. LabVIEW is a digital

Shock Response Spectrum Analysis with a Computer and a Fourier Analyser
2021In this paper the exact definition of shock response spectrum is given. The relation between Fourier spectrum of shock pulse and residual shock response spectrum is discussed with the following relationship: \(S\left(f \right)\, = \,2\pi f \, F(f)\). Finally, with paper introduces the programming of real-time analysing shock response spectrum with a ...

[Development of a shock response spectrum test facility].
Hang tian yi xue yu yi xue gong cheng = Space medicine & medical engineering, 2004To develop a shock response spectrum test facility for testing space products in the pyrotechnic environments.The natural frequencies of the resonant plate, a key part of the facility, were calculated with finite element method. The dynamic response of the whole system was simulated when the machine was excited by a real shock generated by a dropping ...

Time-frequency analysis of shock data with application to shock response spectrum waveform synthesis
IEEE Proceedings of the SOUTHEASTCON '91, 2002The shock pulse synthesis technique, which produces a pulse which satisfies SRS (shock response spectrum) model parameters while maintaining optimal time-frequency (t-f) Characteristics, is considered. Experimental results illustrate the use of t-f information in shock pulse synthesis.

Combining a Fatigue Model With a Shock Response Spectrum Algorithm
Journal of Testing and Evaluation, 2004Abstract Product fragility assessment in packaging is described using a Damage Boundary Curve (DBC), which evaluates the velocity change and deceleration of an input shock for its damage potential to a product. The DBC assumes a brittle characteristic of components.

Shock Response Spectrum Analysis for Measured Earthquake Data
2008Current methods of analyzing signals delivered from vibrations transducers are mainly based on realtime processing in frequency domain. After a shock measurement results a trace that contains a value of a shockâs parameter on the time axis, during its whole action. In earthquake engineering, the parameter usually defines acceleration. Often, this trace
