Wherein the resistance is resisted the regulatory function and is realized through resistance adjusting device, and resistance adjusting device adopts the regulation mode at present to have:
1. electromagnetic resistance control, it differs in that: the controller changes the electromagnetic resistance by changing the intensity of the external current, so as to control the intensity of the drag force to adjust the intensity of the movement;
2. manual resistance adjustment, wherein the motion intensity is controlled by a manual resistance adjuster and a magnetic control device;
elliptical machine of magnetic control device: when the machine runs, the magnet ring at the edge of the flywheel can generate a restraining force on the flywheel, and the smaller the distance between the magnet ring and the flywheel is, the larger the resistance is. The most convenient, effective and simple manual magnetic resistance regulator realizes the distance regulation of the magnet ring and the flywheel in a pull wire and knob mode to control the resistance;
3. mechanical friction force, when the machine runs, the rubber or the friction block made of similar materials is arranged at the edge of the flywheel and is close to the flywheel to generate friction resistance to the flywheel, and independent adjustment is realized at one time.
The resistance adjusting device can well realize resistance adjustment, and then has the following defects:
1. the use of magnetically controlled elliptical machines is very dangerous for users who have auxiliary devices such as pacemakers and defibrillators in their hearts, and requires the necessary protection from magnetic shielding.
2. The elliptical machine adopting the mechanical friction force mode to adjust the resistance needs a more-sliding friction block in due time, and for a user without professional maintenance skills, the elliptical machine does not know that the elliptical machine needs to be replaced properly, can be completed with after-sale assistance, and is also a big problem of after-sale maintenance of products.
In view of the foregoing, there is a need for a magnetic field-free and maintenance-free resistance adjustment device for use by a user having a pacemaker, defibrillator, or other auxiliary device in the heart.

Preferably, the damping fluid is a shear thickening fluid STF, the shear thickening fluid STF is composed of polyethylene glycol and silicon particles, and the polyethylene glycol is a nontoxic liquid with wide application and can bear a wide temperature range. The extremely fine silicon particles are another component of the STF, and when the movement is slow, the hard particles can move around, and the shear thickening fluid STF assumes a liquid state, but when the movement is rapid, the hard particles collide with each other, and the movement of each other is hindered, and the shear thickening fluid STF becomes strong, and the liquid having strong fluidity and the hard particles are combined to form a rigid material.
When the impeller rotates in the shear thickening liquid STF, a shear acting force is formed on the shear thickening liquid STF, the higher the rotation speed of the impeller is, the larger the shear acting force is, the higher the frequency is, the more viscous the shear thickening liquid STF is, and the larger the damping force is provided.
The damper for realizing the above functions at least comprises a closed damper shell filled with damping fluid and an impeller rotating in the damping fluid. The impeller rotates in the damper shell to change the damping force of the damping liquid, so that the resistance adjusting device of the spacewalk machine obtains variable resistance.
