In vehicle development, the validation of individual components can often only be carried out at a late stage by means of real tests and expensive prototypes. If changes are necessary, this leads to high costs and, in extreme cases, to the postponement of the start of production (SOP). To minimize this risk and reduce cost-intensive testing, some tests, such as water or snow tests, are already being replaced by virtual tests.
A reliable tool that accurately simulates both the surfaces wetted by the fluid and the forces acting on the vehicle during such passages is crucial. When calculating the forces on the vehicle components in particular, it is important to simulate the movement of the vehicle body accurate as possible.
Both the movement of the individual wheels in a vertical and horizontal direction, in rotation as well as in movement of the vehicle body, including rolling and pitching movements, must be predicted correctly. In this specific case, this is done using a vehicle model with seven degrees of freedom (7DOF).
In the recently presented PreonLab 6.2, all these effects can be considered with the Full Car Suspension Model (FCSM). Additionally, to these essential movements of the vehicle body, the mass inertia and the resulting forces on the spring-damper system and the surrounding fluid are also calculated.
In our webinar, you will learn about the innovations and advantages of the FCSM in detail and gain an insight into the simplified handling compared to the previous Car Suspension Model (CSM). Using real examples, we will show you the differences between the two models and compare the simulation results with the measurement results.
Key topics and takeaways:
- Advantages of the Full Car Suspension Model
- Usage and comparison with the previous CSM model
- Setting up a water passage with FCSM
- Comparison of the simulation results with the test
