Test device for thermal simulation tester

A test device for a thermal simulation tester, comprising an upper pressure head, a lower pressure head, side shim plates, end shim plates, fixed plates, bolts, washers and nuts, wherein the upper pressure head comprises a cylindrical portion and a flat portion, and a plane of the cylindrical portion is connected to a top side of the flat portion;

• the lower pressure head comprises a cylindrical portion and a flat portion, and a plane of the cylindrical portion is connected to a top side of the flat portion;
• the upper pressure head and the lower pressure head are placed oppositely, and a sample space is reserved between bottoms of the respective flat portions;
• the fixed plates are respectively arranged outside two sides of the flat portions of the upper pressure head and the lower pressure head;
• the fixed plates are provided with grooves at upper ends and lower ends respectively;
• the end shim plates are respectively arranged between the flat portions of the upper pressure head and the lower pressure head and the grooves of the fixed plates;
• and the fixed plates are provided with through holes and fixed by the bolts and the nuts,
• wherein two end faces of the flat portions of the upper pressure head and the lower pressure head are provided with strip grooves perpendicular to bottom surfaces of the cylindrical portions, and in the strip grooves, the side shim plates are arranged between the flat portions and the fixed plates.
