A Case Study for a Bus Body Design Improvement Using Virtual Analysis Methods

CAE (Computer Aided Engineering) has been an important tool in the process of automotive product development. CAE significance has gained ground in the recent years through the introduction of the “No Prototype” vehicle concept. In this essay, an innovative LED destination board implemented to a bus and possible failure on the bus body is investigated using virtual analysis method. Modal analysis has been performed for bus body structure. The resonance of the flexible vibration of bus body has been detected and resonance cancellation has been performed via modal separation in earliest stage of development.
