초록

The vehicle industry requires superior technology that can increase the efficiency of the battery of an electric vehicle. A coolant heater that can optimize the temperature of the battery is one of the most effective techniques for cold environments. However, the vibrations generated by this device can cause major complications, such as leakage and system errors. Therefore, the vibrations of the device must be suppressed to improve the stability. In this study, the fastening conditions of a coolant heater were analyzed using a computer simulation to investigate the natural frequencies and mode shapes which reflect the primary reasons for the largest vibrations under the given operating conditions. The results showed that six-bolted joints could considerably improve the stability of the fastening device
