摘要： 为了保障拟脉冲激励法检测汽车悬架参数的效果，采取了一系列措施。它们是：采用按压激励，采用平板式检测，计算悬架参数族，采用关联维D2和最大L指数λmax甄别样本周期性，选取最大/次大超调量计算阻尼比ξ。将这些措施付诸实施，检测了两种试验车的悬架参数族。结果表明该方法可行。

Abstract: In this paper, some measures for ensuring the effect of inspecting vehicle suspension parameters by the quasiimpulse excitation are proposed. They are the excitation with press bodywork; the plate inspecting; the calculation of suspension parameters; adopting the criterion of the correlated dimension D2; recognizing the periodicity of samples with maximal Lyapunov index λmax; and selecting the maximum/submaximum values in the samples to compute the dampingratio ξ. With these measures, the parameters of the suspension systems of two testing automobiles are inspected. And the results show that the measures introduced in this paper are feasible.

Key words: vibration and wave, quasiimpulse excitation, suspension system, suspecting, press bodywork
