1. A vibration-centrifugation composite test apparatus, comprising:
a centrifuge, an air-cooled electric vibration table and a control electrical cabinet; wherein
the centrifuge comprises a base, a rotation arm is horizontally disposed on the base, and a middle portion of the rotation arm is connected relative to the base so that the rotation arm is rotatable about a vertical direction line extending through the middle portion; a driving device acts on the rotation arm to drive the rotation arm to rotate relative to the base;
one end of the rotation arm serves as a load end, a counterweight serving as a balance end is disposed at the other end, and a conductive slip ring is disposed in an interior of a rotation center of the rotation arm;
a vibration table main machine in the air-cooled electric vibration table is disposed inside the load end of the rotation arm, a moving coil is disposed in the vibration table main machine, the moving coil vibrates in a horizontal direction, and a central axis of the moving coil is on the same straight line as a horizontal center line of the rotation arm;
the control electrical cabinet is mounted above the rotation center of the rotation arm, a power supply line of the control electrical cabinet is connected to a power supply through the conductive slip ring, and a vibration feedback signal line of the vibration table main machine bypasses the conductive slip ring and is directly connected to the control electrical cabinet;
wherein the air-cooled electric vibration table comprises the vibration table main machine and a fan, the fan is connected with the vibration table main machine through an air duct and is mounted at the middle portion of the rotation arm;
wherein the rotation arm comprises a set of main beams, a plurality of cross plates connected between the main beams, each of the cross plates is provided with a through hole, and the air duct transversely passes through the through holes; and
wherein the air duct is connected to the vibration table main machine along the horizontal direction.
