1. Hällman, Emil. Provning och modellering av genomslagsgummin implementerat för dynamisk simulering i MBS.

Degree: 2014, Luleå University of Technology

Bump stops are components used in the truck chassis for the wheel suspension and cab suspension. Their main purpose is to reduce the impact between e.g. front axle and frame when the suspension bottoms. In these situations, the bump stop undergoes compressions with large deformations and high velocities. The dynamics of these components are difficult to describe since the material characteristics for rubber are highly non-linear.The simulation models that are available for the MBS software Adams are highly simplified and do not describe these events in a satisfactory manner. Hence the goal for this thesis work was to develop a simulation model for bump stops based on the results from dynamic testing. The simulation model uses the variables displacement and velocity to calculate the force being transferred through the bump stop. Four different bump stops were subjected to quasi-static and dynamic loading while the force and displacement were measured. The experiments were carried out in a hydraulic press and a test rig designed for this purpose where several weights were dropped onto the bump stop from different heights.A simulation model consisting of an elastic and a visco-elastic force response along with a rate-independent friction model was derived based on the experimental data. The model includes 14 parameters that can be identified through quasi-static and dynamic measurements of the particular component.A subroutine was written in order to implement the proposed model in Adams and a virtual model of the test rig was created. A number of dynamic simulations were performed in order to verify the model by comparing the results to experimental data.A FE-analysis was carried out on two of the tested bump stops and it was found that some of the bump stop characteristics could possibly be obtained without performing any experiments on physical components.
