Methodology for the Analysis of Virtual Deformation of Flexible Elements Associated with the Engine Displacement 2015-36-0171
Through computational dynamic simulations is possible to achieve high reliability index in the development of automotive components, thereby enabling the reduction of cost and time of a product development with considerable gain in quality.
This work suggests the validation of a methodology for simulation where is possible to improve the confidence level for design flexible components, such Heater and Cooling hoses that are under dynamic engine action, in relation to the physical model.
Known the difficulty in predicting non-linear mathematical relationship deformation under effect of forces and moments, was established a study based on experimental measurements where were used as input parameters to simulate the dynamic behavior of flexible components, in this case, coolant hoses.
Using IPS (Industrial Path Solutions) software to build the model to be simulated, the mechanical and geometrical properties have been assigned to each component and its thermal deformation as well, with the aim of obtaining virtually the real deformations in stationary condition, causing with the virtual static model represents accurately the experimental model.
Finally, was established a dynamic routine to the model, simulating the characteristic movements of the engine and transmission assembly, thus yielding the behavior of flexible elements in a given situation in order to verify if the component meets the package requirements, avoiding undesired dynamics interference and early degradation of each component.
