Modal Analysis Comparison on Dipstick Holding Bracket with and without Use of Vibration Isolator

Vidhi Atasniya, Ashesh Tiwari

Abstract: The paper discusses use of damper (vibration isolator) on Dipstick holding bracket in an Automobile application such as off highway Excavator vehicle. Is it necessary to use isolator or not An excavator is heavy machine used to dig earth mantle, hence it has to undergo very high vibrations. All parts of excavator should sustain these vibrations and perform function with desired efficiency. The dipstick of Excavator is generally very long and needs to be supported at more than one location on engine cylinder body. In general, all excavators use vibrations isolator along with P-Clip and Bracket at holding locations away from Engine Base (in some case Chassis) because intensity of vibrations is higher at parts away from Base. But this is observed that Modal Analysis of upper holding bracket with and without the use of Vibration Isolator didnt differ much and hence Vibration Isolator can be removed finally resulting in cost reduction and optimization of system
