Dynamic Transient Simulation to Predict Durability Loads from Road Load Profile under Linear Assumptions 2021-01-0831
Structural durability of the vehicle components is one of the key factors in design and development. This helps in understanding the capability of structures or components to withstand the loads encountered in service over a specified period of use.
Durability assessment for vehicle structures requires load inputs. These load inputs can be in form of force, acceleration and displacement and typically generated from road load profiles in the testing lab or by the load groups. But if a program is in its early stage when design data is immature or lab facility is limited then acquiring these load inputs takes time and sometimes not feasible also. In this scenario, we can predict the durability load inputs from road load profiles virtually using dynamic transient simulation.
The objective of this work is to predict the durability input signals from road profiles using finite element model by modal transient approach. These inputs can be further used for quantitative or comparative validations of durability assessment for multiple sets of road load or design data to various sub systems.
