Abstract

The invention provides an impact test device for an energy consumer and an impact test method thereof, including: a support system with adjustable height and balance moment, a guide and limit device that can adapt to the deformation of the energy consumer, and a rope for integrated switching of lifting and loading Guided force transmission mechanism, integrated force-deformation synchronous test system and maintenance operation platform for convenient test operation. The device described in this application limits the extension path of the energy consumer, and integrates a laser displacement meter and a force sensor to form a test method for dynamic and synchronous collection of key information on impact mechanical responses. The invention provides a special impact test device and method for obtaining nonlinear force-displacement data information of energy-consuming components of a flexible protection system.

Description

technical field [0001] The present application relates to the fields of slope geological hazard protection, impact mechanics and flexible protection engineering, in particular to an energy dissipator impact test device and a force-displacement synchronous test method, which are suitable for impact tests and non-contact tests of energy dissipating components in flexible protective structures. Acquisition of linear force-displacement data. Background technique [0002] In the field of rockfall disaster protection, flexible protection systems are often used in disaster prevention and control, and energy-consuming components are critical to the impact resistance and energy dissipation capabilities of flexible protection systems. At present, "energy-consuming components should be tested for dynamic performance" has been included in CECS "Technical Regulations for Passive Flexible Protection Nets", Ministry of Transport "Slope Flexible Protection System" and Ministry of Railways "...
