| Abstract [eng] |
Experimental research of hydraulic cylinder type resistance devices at different operating regimes (piston speed and resistance level) has been performed by means of universal computer controlled benchtop materials testing machine “Tinius Olsen H25K-T”. The samples were taken from different brands exercisers where resistance is generated by the pair of cylinders: three mini steppers and three rowing exercisers (these with manually adjustable resistance). The research showed that hydraulic cylinder type loading devices of exercise machines generate quite uneven resistance force: depending on the operation regime its variation reaches up to 30 % of nominal size. According to the results of investigation it may be stated that the nominal resistance force depend on the cylinder used (is different for the same design cylinders of different vendors), so it is important to use proper cylinder when replacing broken or worn unit or even both cylinders have to be replaced to ensure symmetry of resistance. |
