Abstract: The battery set up is used in many applications like hydraulic excavator, Mining Tucks and Electrical vehicles technology etc. In this project this particular battery setup used in the especially in the Hydraulic excavator. The project is regarding the dynamic analysis of Battery unit for Hydraulic Excavator. Here in the dynamic analysis 3 types of analysis is performed. The modal analysis, Harmonic response and Random vibration analysis is performed on the battery unit. By using modal analysis, we get the value of the natural frequency for different mode shape. Random vibration analysis mainly used to check the behavior of the system when the structure subjected to random load. Random load means value can’t be determined precisely in the advance. Random Response or vibration analysis input is given in the form of power spectrum density, and we get the value of RMS value in the form of sigma means stress value. By using Frequency Response analysis, we get Displacement vs Frequency and acceleration Vs Frequency. Modal analysis the External force/excitation effects are not considered and also not considered the damping effect, but in the case of frequency response analysis External excitation force and damping effects are considered. By Applying appropriate loading and boundary constraints in the battery unit by using Modal analysis we get different value of Natural frequency for Different mode shape and by using Frequency Response analysis by using acceleration vs frequency we get the value of Maximum acceleration at frequency so that we need to avoid it and by using random response analysis we get the value of RMS (Maximum stress) Value. For Finite Element Analysis, pre-processing is done on the hyper mesh 19.1 and analysis is carried out in Opti-struck package.
