Finite Element and Experimental Investigation on the Effect of Repetitive Shock in Corrugated Cardboard Packaging [PDF]
Journal of Applied and Computational Mechanics, 2021 The primary concern of the current study is estimating the repetitive shock induced damages leading to cumulative fatigue on corrugated cardboard boxes experimentally and numerically. Repetitive shock tests were performed on boxes using a vibration table

A Thermal Actuated Bistable Structure for Generating On-Chip Shock Loads
Micromachines, 2022 In this paper, we propose a bistable shock structure based on the thermal actuation principle, which overcomes the response time limitation of heating and cooling in typical thermal actuators and enables a rapid release of energy.

Approximate computing of shock response spectrum using reduced impedance method
Nihon Kikai Gakkai ronbunshu, 2021 This paper presents an approximate computing method of a shock response spectrum induced by a drop-weight shock test. The proposed method is based on a reduced impedance method, and computes the shock response spectrum by synthesizing the vibration ...

EXPERIMENTAL SPECIFICATION OF THE IMPACT OF MECHANICAL PARTS AND HYDRAULIC OIL CONDITION ON VEHICLE SHOCK ABSORBER PERFORMANCE IN ENERGY DISSIPATION [PDF]
Proceedings on Engineering Sciences, 2019 The purpose of a damper, or so-called ‘shock absorber’, is to introduce controlled friction into the suspension system and dissipate the incoming-to-vehicle energy due to external excitations, in order to give dynamic stability to the vehicle. As damping
