Abstract [eng] The mathematical model of MR fluid flow in an annular channel of the MR shock‑absorber taking into account forces of dry friction and gas friction in a pneumatic camera, dependence rheological properties of the MR fluid on shear rate, temperature and magnetic flux density is developed. Performance characteristics of the MR shock-absorber (dependences of force on value of control electric signal taking into account of shock-absorber geometry, rod displacement, rheological properties of MR fluid, temperature) are calculated. The analysis of influence of the magnetic field and temperature values on the MR shock-absorber performance characteristics depending on amplitudes and frequencies of piston movement is carried out. The resistance force with growth of magnetic flux density increases 40 times. But the resistance force with growth of temperature from 20°C to 80°C decreases 7 times, in an magnetic field ( 500 mT), and 2 times, without a field ( 0 mT).
