Shock Response Spectrum Calculation from Container Placing
2019 20th International Carpathian Control Conference (ICCC), 2019This paper deals with using shock response spectrum for container placing optimization. Two types of laying pads under container are used and its impact to container substructures is observed. Shock response spectrum is calculated with using Signal Analyser software from signal measured with accelerometers during container placing.

Shock Response Spectrum Testing With Shock Machine
, 2019 Transient mechanical shocks cause dynamic stress in structures which results in defect or malfunction of exposed devices. A shock response spectrum (SRS) is used for characterizing an acceleration response of linear single degree of freedom system to these shocks.

Method to Predict the Shock Response Spectrum Shape from Frequency Response Functions
, 2017 In an effort to understand the details of why a Shock Response Spectrum (SRS) has a particular shape, a method was designed to predict the shape of the SRS based on Frequency Response Functions (FRFs). Gaining a full understand of the relationship between the FRF of a structure and the SRS shape should prove to be very useful in reducing SRS test time ...

Critical Shock Response Spectrum of a Beam Under Shock Loading
Volume 9: Prof. Norman Jones Honoring Symposium on Impact Engineering; Prof. Yukio Ueda Honoring Symposium on Idealized Nonlinear Mechanics for Welding and Strength of Structures, 2016The offshore structures experience severe shock environment caused by storms, episodic waves, icebergs or supply ships. The aerospace equipment may also encounter severe shock loadings due to pyrotechnic shock. The intensive shock causes structural failures, or even results in fatal consequences on the related facilities and persons.

Simulation of pyroshock environment and effect rules of shock response spectrum
The Aeronautical Journal, 2023AbstractThe high-frequency and high-amplitude pyroshock environment during the service of the spacecraft will cause damage to the equipment. Here, we develop a shock test device based on air cannon to simulate the above pyroshock environment. Then, a finite element model was established by explicit dynamic software ANSYS/LS-DYNA, and the simulation ...
