DESIGN AND ANALYSIS OF VIBRATION AND HARSHNESS CONTROL FOR AUTOMOTIVE STRUCTURES USING FINITE ELEMENT ANALYSIS

Many machines and machine mechanisms run under dynamic working conditions. The vibrations produced under dynamic conditions affect many important designs Parameters such as strength, production costs, productivity. Computer aided engineering (CAE) procedures are used to analyses the dynamic Response of the vibration controls. The finite element methods used in the analysis are Applied by a computer aided design and analysis software ANSYS. The aim of this paper is to study existing design automotive structures can operate safely environment to reduced vibration resonances. An ANSYS APDL code is developed to obtain the time- histories to frequency range of model and transient analysis APDL stands for ANSYS Parametric Design Language.
