汽车悬架隔振性能评价方法

Evaluation Method for Anti-Vibration Performance of Auto Suspension

给出3种评价汽车悬架隔振性能的方法并予以讨论。基于线性系统频域分析的常规评价方法有一系列不足之处,但目前仍是主流方法。混沌评价方法的力学前提与悬架动力学特征吻合,但其应用尚待时日。将人工主观评价和综合参数评价相结合形成综合评价方法,是评价汽车悬架隔振性能乃至整车舒适性的有效手段。

The three kinds of evaluating methods for anti-vibration performance of auto suspension are offered and discussed, The general evaluating method, which is based on the linearity analysis in frequency domain, is still a primary one although there are a series of shortage in the technique. The chaotic evaluating method, whose mechanics premise meets the dynamics characteristic of auto suspension, is yet far from application. The integrative evaluating method, which is combined with the subjective manual evaluation and synthetical parameter evaluation, is going to be an effectual method to evaluate the anti-vibration performance of auto suspension as well as the whole auto harshness.
