传统摩擦阻尼健身车是通过调节摩擦带与摩擦轮之间的压力而调节摩擦力大小，锻炼者骑行过程中输出自身能量克服健身车摩擦力而做功，从而达到强身健体的目的。功率自行车利用现有健身车结构，量化了摩擦带与摩擦轮之间的加载负荷，并通过系统受力分析，确定了加载质量、骑行转速与被测试者输出功率之间的数学关系，从而实现了对被测试者功率消耗的测定，为传统的经验锻炼向科学量化锻炼提供了有效工具。本文通过系统分析，为摩擦阻尼式功率自行车设计提供了理论依据。

The traditional cycle with friction damper adj usts the frictional force by adj usting the pressure between friction belt and friction wheel,the cyclist can tone up his/her body by working to overcome the friction of cycle during the cycling process.By using the structure of the existing cycle,cycle ergometer can test the consumed power of the testers by quantifying the loading be-tween friction belt and wheel,determining the numerical relations of loading,rotating speed and output power of the tester.It pro-vided an effective tool for the transition of exercise from traditional,empirical one to quantitative,scientific one.Meanwhile,the pa-per laid the theoretical basis for the design of cycle ergometer through a systematic analysis.
