Weight Optimization and Structural Analysis of an Electric Bus Chassis Frame
Keywords:Aluminium alloys, ANSYS, Electric bus chassis frame, Structural analysis, Weight reduction
Major cities have seen an increase in motorization in recent decennium, accompanied by deteriorating/poor air quality. Electric buses shows a major obligation in this regard, as these buses have several advantages in respect of lowering noise, pollution, and fuel consumption. Additionally, the costs of keeping an electric bus are around 25% less expensive than those of maintaining a diesel bus, due to the fact that the electric engine does not require the same level of maintenance as a diesel engine. Furthermore, the negative aspect of the electric car is the battery's long-term endurance power. The more energy it takes to run a bus, the heavier it is. It is preferable and more effective to keep the weight of the vehicle elements as low as possible. Our research is focused on the chassis frame, which is an extremely important component of the bus and plays a significant role in supporting the structural safety and strength of the vehicle while also playing an important role in determining the overall weight of the vehicle, which has an impact on the vehicle's performance. This is why we chose the chassis frame as the subject of our investigation. Steel is typically used for the frame since it is sturdy, but it is also heavier and adds weight to the entire bus, diminishing operational effectiveness. The purpose of this post is to illustrate how to reduce the weight of an existing electric bus by replacing its steel components with lightweight aluminium alloys that are both safe and structurally sound while retaining the safety and structural integrity of the frame and chassis. The integrity of the structure is critical in ensuring a safe design. A structural study of the projected chassis frame model will be undertaken using the ANSYS 20.0 simulation programme, using stress and deformation as design constraints, in order to provide a more secure design.
