Impact dynamics research facility for full-scale aircraft crash testing [PDF]

open access: yes
An impact dynamics research facility (IDRF) was developed to crash test full-scale general aviation aircraft under free-flight test conditions. The aircraft are crashed into the impact surface as free bodies; a pendulum swing method is used to obtain ...

Analysis of Contact Line Short-circuit Current Thermal Effect of Electrified Railway

open access: yes机车电传动, 2019
In order to study the thermal effect of railway contact line in passive short circuit and power failure, the temperature rise between the main circuit, the pantograph slide and the contact line of the catenary caused by short-circuit current was studied.

Investigation of 3D steel frames with a reduced beam section and various web-opening shapes under internal column loss

open access: yesJournal of Asian Architecture and Building Engineering
The sudden loss of columns due to abnormal loads demonstrates a remarkable example of a localized failure that might ultimately result in the progressive collapse of the complete steel-framed structures. In this study, finite element (FE) simulations are
