variable sky meaning in Chinese

多变云天

In addition , taking one engine mounts design into account , the paper investigates and compares some types of design schemes and shows that semi - active continuous variable damper is feasible and applicable . the numerical simulation results further proves that the continuous variable sky - hook damper is able to effectively isolate the engine vibration , so the damper has promising value in the engineering field
另外，以某发动机悬置的设计为背景，比较了各种设计方法，论证出半主动连续可控阻尼悬置为最佳的方案，并用简化的悬置模型进行了数值仿真分析，通过得到的振动性能的比较，表明按天棚阻尼设计的连续性半主动悬置系统，能够有效地隔离发动机振动，有很好的工程应用前景。
