Abstract

The invention discloses a linear-motion electromagnetic loading device which comprises a linkage mechanism, a magnetic powder loader part and an electrical control part. A loading head passes through a linear rolling guide sleeve in the linkage mechanism. One end of the loading head is connected with a one-way tension and pressure sensor. The other end of the loading head is connected with a crank pin through a connecting rod and a threaded sleeve. The magnetic powder loader part is characterized in that: a circulating cooling water channel is arranged in an inner cavity of a stator; a magnetic powder is arranged in a gap between a rotor and the stator; a loading coil is arranged on a circle surface in a stator shell; the rotor is connected with a main shaft and a disc; the disc is provided with the crank pin through a trapezoid sliding block. The electrical control part comprises a loading controller and an industrial control computer. By using the apparatus of the invention, performance analysis and test loading of a prime mover and a mechanical system possessing a linear motion output member can be realized. A constant loading current is used to obtain a variable loading force. The small loading current is used to obtain the large loading force.

Description

technical field [0001] The invention belongs to the technical field of performance detection and testing of electromechanical equipment systems, and is used for performance analysis and testing of a mechanical system with a linear motion output component and a prime mover thereof, in particular to a linear motion electromagnetic loading device.
