    摘要: Seismic wave simulation apparatus (1) includes an elastic energy accumulator (4) shaped to induce a simulated seismic wave of known form in a geological specimen (2) in which is embedded the foundation (3) of a building. A hydraulic actuator (5) is used to preload the accumulator (4) in a direction reverse to arrow A and an explosive bolt (6) is exploded, thereby releasing the energy of the accumulator (4) as a seismic wave through the geological specimen (2). The specimen (2) is provided with transducer bars (8) and an electrified metallic thin sheet (9) connected to a Wheastone bridge in order to obtain various measurements.

    摘要: FIGURE 1 shows pulse generation apparatus (1) including a impactor bar (2) that can be pre-loaded in a direction reverse to arrow (A) by hydraulic actuator (3). Bolt (6) is exploded whilst the impactor bar (2) is pre-loaded thus releasing said bar into impact with the front end of bus (B), generating a compression wave of known characteristics through the bus structure to simulate a crash scenario. Transducer bars (8,9) are arranged to take measurements from critical points of the bus structure.
