均方根值法SUV排气系统挂钩悬挂位置确定
Root mean method determines the suspension position of the SUV exhaust system
摘要
Abstract
The inaccurate selection of the suspension position of the exhaust system can easily lead to abnormal noise and vibra-tion during the driving of the car,and it is extremely important to accurately select the position of the suspension point of the ex-haust system.The position value extracted from the vibration mode of the exhaust system is weighted and processed by the Root Mean Square(RMS)method to obtain the root mean square value method suspension point layout of the vibration mode displace-ment.The position of the suspension points arranged by the Average Driving Degree Of Freedom Displacement(ADDOFD)meth-od and the suspension points obtained by the root mean square method are compared and verified.The results show that the root mean square method of suspension point arrangement is effective in SUV.The root mean square method has a higher distribution efficiency than the average driving degree of freedom displacement method.Shortened design cycles.关键词
