ADAMS_Based Research on Vibration Isolation Performance of Powertrain Mounting System
Xiaozheng Li, Ke Chen
The vibrations of vehicle engine powertrain is one of the main vibrations sources of whole vehicle. Severe vibrations can not only cause the vehicle structure fatigue and damage, but also affect the durability and comfort of the vehicle. What’s more, it can influence interior personnel's physical health....
Research on High-frequency induction brazing of PCD Cut Tool
Bei Sun, Miao Yang, Zhiyi Zhang
The morphologies of the brazing fill are studied by SEM and EDS. The binding force and use life of PCD cut tool are studied too. The results shows that the quality of weld fill is the best when time is 13 and 15s. Meanwhile, the weld fill shows metallurgical bond. The Interdiffusion of matrix alloy and...
Life Prediction of Existing Concrete Structures in Acid Rain Environment
In the paper based on diffusion theory the acid rain erosion-carbonization model was established. The model parameters were analyzed and the model was solved by MATLAB software. At same time the failure criteria of existing concrete structure in acid rain area was developed and the life prediction method...
