Earthquake Simulation Using Linear Motion Stages

Product Announcement from H2W Technologies

Earthquake Simulation Using Linear Motion Stages-Image

With the goal of safer buildings and saving lives, scientists and engineers, through the simulation of many recent earthquakes, need to test building materials and structural designs. Using either a one or two-axis high force linear positioning stage from H2W Technologies, they can simulate the effects of earthquakes as large as the largest recorded earthquake in history, the 9.5 magnitude quake on the open-ended Richter scale, in May of 1960 in Chile.

To generate the high forces accelerations necessary to simulate different types of earthquakes, including a transform plate boundary quake (a destructive type of earthquake), H2W uses three-phase brushless motors with Hall Effects guided by linear ball bearings.

H2W also manufactures a line of high force linear positioning stages that have single-axis operation. This stage has a standard continuous force of 84 pounds [374 N], and a stroke of 8 inches [0.2 meters], although longer strokes and higher forces (up to 250 pounds [1113 N] continuous) are readily available. H2W will design a customized stage to meet a customer's specific needs.

Key Features
