Abstract

The invention discloses a fatigue test device for planar springs, which includes a machine table, the machine table includes a support, a driving mechanism and an AC power supply, the planar spring to be tested is arranged on the support, and the driving mechanism includes an electromagnetic Mechanism, piston and piston rod, the electromagnetic mechanism is connected with the AC power supply, the AC power supply drives the electromagnetic mechanism to generate a magnetic field, the piston is provided with a permanent magnet, the piston is placed in the magnetic field, the The magnetic field drives the piston to reciprocate in the magnetic field, the two ends of the piston rod are respectively connected with the piston and the planar spring, and the reciprocating piston drives the planar spring to vibrate through the piston rod. The technical solution of the invention is simple in structure, reasonable in design, easy to manufacture, and can rapidly carry out the fatigue test of multi-vibration times of the plane spring.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing and relates to a fatigue testing device suitable for planar springs in Stirling motors. Background technique [0002] The planar spring in the Stirling motor needs to vibrate hundreds of millions of times per year on average during its working process, so the qualified planar spring in the Stirling motor must have high strength. However, in the prior art, there is a lack of fatigue testing devices for testing planar springs with a relatively large number of vibrations. [0003] Patent CN104089763A discloses a spring fatigue testing device, which includes a pressure sensor, a control panel, a support body, a cam, a transmission mechanism that drives the cam to rotate, and at least one spring clamping mechanism, and the spring clamping mechanism includes a follower piston assembly and a base assembly , the follower piston assembly is slipped on the support body, one end of the follower p...
