Land mine simulator

摘要

A land mine simulator includes a housing having an opening formed in one end thereof. A plate movably supported in the housing's opening has a first face exposed to a surrounding environment and a second face exposed to an interior region of the housing. A non-compressible fluid-filled reservoir in the housing includes a flexible diaphragm opposing and spaced apart from the second face of the plate. Plungers are between each of the second face of the plate and the diaphragm. Each of one or more air spring in the housing includes a cylinder having a movable piston sealed therein with a first side of the piston in fluid communication with the reservoir's fluid and a second side of the piston in fluid communication with a pressurized volume of gas within the cylinder. A pressure sensor is provided in communication with the fluid in the reservoir.

主权项

1. A land mine simulator, comprising:
a housing having an opening formed in one end thereof; a rigid plate movably supported in said housing at said opening thereof, said plate having a first face adapted to be exposed to a surrounding environment and a second face exposed to an interior region of said housing; a reservoir disposed in said housing, said reservoir including a flexible diaphragm opposing and spaced apart from said second face of said plate; a plurality of plungers disposed between and in contact with each of said second face of said plate and said diaphragm; a non-compressible fluid filling said reservoir; at least one air spring disposed in said housing, each said air spring including a cylinder having a movable piston sealed therein, wherein a first side of said piston is in fluid communication with said fluid in said reservoir and a second side of said piston is in fluid communication with a pressurized volume of gas within said cylinder; and a pressure sensor in fluid communication with said fluid in said reservoir.
