根据我们以前的研究，着陆冲击载荷很好地识别使用非线性非对称粘性的vscoelastic模型。使用该模型，着陆冲击载荷的可变性表示在模型参数上。为了考虑不同跑速的变化，我们测量了60个在三种不同的速度，3 m/s，4 m/s和5 m/s的稳定配速跑的着陆冲击载荷。结果总结如下：（1）尽管着陆冲击载荷的变异性很小，但模型参数和每个单元产生的力序列的变异性很大，但也观察到大的变异性之间的独立性，（二）观察到低质量和非线性不对称粘性和非线性弹性元件产生的冲量的大的变化，3 m/s运行。
According to our previous studies, landing shock loads are well identified by using the vscoelastic model with nonlinear unsymmetrical viscosity. Using this model , variability of landing shock loads is represented on the model parameters . To consider the variability in different running velocities, we measured 60 landing shock loads during steady pace running at three different velocities, 3m/s, 4m/s and 5m/s . The results are summarized as follows: (1) a large variability in the model parameters and the force sequence produced by each element was observed in spite of small variability of landing shock loads, but there was also observed an independency between the large variabilities, (2) a large variability of the lower masses and that of the impulse produced by nonlinear unsymmetrical viscosity and a nonlinear elastic element was observed in 3m/s running.
