WebMar 25, 2024 · 2024-01-1418. Performance criterion of local stiffness in BIW (Body in White) for NVH (Noise, Vibration, and Harshness) and R&H (Ride and Handling) are … WebFeb 8, 2024 · This paper describes a new approach of identifying the contribution of each joint in a BIW toward the overall stiffness of the BIW. The joints in the BIW are parametrized and Altair Optistruct [ 1] tool is used to find optimum value of each parameter. The contribution of different joints to the overall stiffness is different for different loads.
GLOBAL STIFFNESS ANALYSIS OF BIW STRUCTURE
WebMar 4, 2013 · Stiffness is crucial for designing automobile BIW structure. Stiffer is generally considered to be better. Prediction based on the local gauge sensitivity yields the stiffness changes due to local gauge modification.The results will assist gauge optimization of automobile BIW -driven design.The following WebDynamic stiffness analysis is simply FEA simulation run with the aim to define first and second BIW natural frequency (BIW first and second self-excitation frequency modes). It’s also an excellent tool to control local NVH (Noise, Vibration, Harshness) issues effecting occupants comfort, like resonance in a car body generated by vibrating ... simple fish pie
