Design and Testing of Shock Transmission Device for Bridge Protection

Abstract:

The design of the shock transmission unit (STU) was based on the maximum displacement, nominal load, lock up velocity and other parameters. The STU was subjected to a series of tests for checking its behavior. During the slow movement test, the resistance force is 10kN; during the simulated dynamic test, the deflection between the point of zero load and the point of maximum load is 4mm, and the deflection during the sustained load portion of the test is 5mm; during the fast movement test, the STU locked up within 1mm, the deflection from the point of lock-up to the maximum test load is 5mm, and the stiffness of STU throughout the force range from lock-up to maximum test load in tension and compression is 7.72% and 3.6% respectively. During the overload test and the fatigue load test, the STU shows no sign of leakage or binding.
