摘要： A testing machine includes a base, at least a pair of columns joined to the base and a crosshead joined to the columns at a location spaced apart from the base. At least a pair of specimen holders are provided. A first specimen holder is supported by the crosshead and faces the base, and a second specimen holder is supported by the base, the base being that portion joined to each of the columns closest to the crosshead. An actuator connected in series between one of the specimen holders and the corresponding base or crosshead. A brace connected to each of the columns and spanning between the columns, the brace being connected to each of the columns at a location along a length thereof between the base and the crosshead.

摘要： An electric actuator includes a stationary support and a guide system having a single stationary guide joined to the stationary support having an axis. The actuator also includes a stationary assembly secured to the stationary support. A moving assembly is movable relative to the stationary support on the guide, where the moving assembly and the stationary assembly provide at least two sets of interacting magnetic fields disposed about the guide at equal angular intervals. A test specimen support is joined to the moving assembly and disposed on one side of the stationary support so as to move along the axis with movement of the moving assembly, the axis extending through the test specimen support.
