Discussion on linear motor exploration device based on recent seismic events. At 8:02 a.m. on December 5, a 4.5-magnitude earthquake struck the Fengnan District district of Tangshan, Hebei Province. According to the research and analysis of experts from China Seismic Network Center, this earthquake belongs to a normal fluctuation activity in the aftershock area of Tangshan earthquake in 1976. What's an aftershock? It's been forty 1976 Tangshan earthquake years, and there's still a threat? 

     The so-called aftershock is a relatively large earthquake, in its focal area and adjacent areas will occur in some significantly increased seismic activity. The size of the aftershock area is related to the magnitude of the main shock, and the larger the magnitude of the main shock, the larger the aftershock area. These aftershock activity gradually decays over time, eventually transitioning to a low level of seismicity known as a "normal" background earthquake, although this time is variable, long or short.

      Earthquake, as a common geological disaster, brings huge disasters and losses to human beings. For a long time, China has invested a lot of financial and material resources in the research and development of Earthquake warning system and seismic exploration devices In order to reduce casualties, reduce losses. It is reported that in recent years, the relevant departments have found a new breakthrough, and are studying a shallow s-wave seismic exploration source device based on a linear motor. A connecting module is fixed in front of the mounting module The linear motor is fixed on the concave surface in front of the vertical plate stator connecting plate of the connecting module, and the movable element is fixed on the back of the movable slider connecting plate of the hammer module, and the movable movable slider connecting plate is fixed on four linear guide rail slides The linear guide slide is mounted on the front of the two linear guide rails, the two linear guide rails are fixed on the convex surfaces at the two sides of the front of the vertical plate stator connecting plate of the connecting module, and the heavy hammer is fixed on the front of the movable slider connecting plate The bulkhead is directly below the weight, and the control box is on the left side of the whole device.
