Using TCL/TK on HyperWorks to Study and Develop the Process Automation of Bus Rollover Simulation

Bus is a high capacity vehicle on transportation. Once accident happened, such as rollover, crashes, etc.., it will cause terrible injury to passengers. Therefore, the research in the strength of superstructure is an important topic in the world. Apply the CAE (Computer Aided Engineering) to analyze the bus structure, this method not only assist bus manufacturer decrease the time and cost of new vehicle development, but also understand the structure characteristic under different situation, such as strength, stiffness and anti-crash characteristic, on the other hand, it also can accumulate the analysis data and create the database for bus structure design.

The research in this thesis is using the ECE R66 (Regulation 66 of the Economic Commission for Europe) to simulate the rollover of buses. Nowadays, the cost of time still quite expensive in CAE, we are looking forward to simplify the process by using TCL/TK (Tool Command Language/Tool Kits) and HyperWorks. Developing the process automation of bus rollover simulation and create the report automatically can decrease the time cost in this CAE process. This process automation can reduce the time cost for 10 hours and human mistakes in every rollover simulation, it also increase the quality control in every simulation. We expect this automation technology can apply to other filed and make the process faster in future.
