Abstract: The present disclosure provides a system and method for measuring energy conversion efficiency of an inertia friction welding (IFW) process in a non-contact manner. The system includes an IFW machine, a Hall sensor, a data acquisition module, a processing module and a stabilized direct current (DC) power supply. The stabilized DC power supply provides electrical energy for the Hall sensor. The Hall sensor is provided beside a flywheel of the IFW machine, so that the flywheel is within a detection range of the Hall sensor. A magnet is provided on the flywheel. The data acquisition module acquires a Hall electric potential change caused by a relative movement between the magnet and the Hall sensor during the IFW process, and transmits the Hall electric potential change to the processing module to calculate the energy conversion efficiency of the IFW machine.

Abstract: An intelligent vehicle capturing apparatus for a high-pier bridge includes: a double-layer metal protective net; and a support unit and an actuation unit connected to the double-layer metal protective net. The double-layer metal protective net is mounted to a backside of the high-pier bridge through the support unit. The actuation unit includes a hydraulic link mechanism. The hydraulic link mechanism is connected to one end of the double-layer metal protective net. The hydraulic link mechanism is moved to unwind the double-layer metal protective net on the backside of the high-pier bridge to capture a vehicle. In this way, the apparatus stops and buffers a vehicle that is about to rush out of a high-pier bridge.
