bearing, connecting rod meaning in English
连杆轴承
Examples
- The reassigned smoothed pseudo wigner - ville distribution ( rspwvd ) is introduced , which has less interference and higher resolution than other time frequency distributions like wigner - ville , choi - williams etc . it is used to detect the multi - knocking of engine such as cylinder , piston pin , valve , crank bearing , connecting rod bearing and jib knocking . a new fault diagnosis technique based on the rspwvd for the engine multi - knocking problem is proposed . by comparing the bispectrum and bicoherence of the gear vibration signals , it is demonstrated that bispectrum has an advantage over bicoherence for feature extraction of such signals
第四章首次引入一种重分配方法，得到干扰项少而分辨率高的重分配平滑伪魏格纳维尔分布( rspwvd ) ；对发动机曲轴主轴承响、连杆轴承响、活塞销响、活塞敲缸响、气门响和挺杆响等常见机械异响故障振动信号特征进行了全面地比较分析；通过对各种异响故障特征信号的分析研究，提出基于rspwvd的发动机多异响故障诊断策略，利用该策略可以准确识别不同的发动机异响故障。 - In the simulation , the mpc technique of msc . nastran is used to simulate the mechanical behavior of contact between the interfaces of piston pin and bearing of small end , crankpin and big end bearing , connecting rod body and bearing cap ; also constraints are applied to the connecting rod reasonably
分析中采用了patran中的多点约束( mpc )技术，有效地模拟了活塞销与小头孔内表面、曲柄销与大头孔内表面以及连杆体与大头盖接触面的力学接触状态，并对连杆进行合理的约束。
