曲轴主轴承 - The fifth chapter makes a technological analysis to the engine bolt on the whole and put forward the application of plasticity out of shape district control law and elasticity out of shape district corner control law to the keys parts of the engines , including connecting rod and main bearing
第五章对发动机螺栓紧固技术作了技术分析，提出了塑性变形区控制法和弹性变形区转角控制法在发动机关键部位螺栓，如连杆、曲轴主轴承盖上的应用。 - 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。
