Bellows can be used as collapse elements for automotive steering columns. The crash performance of the steering column can be significantly improved with the bellows. However, the bending flexibility of the bellows has negative effects on the vibration characteristics. An effort is made to improve the vibration characteristics of steering columns with bellows. To understand the effects of various design parameters on the collapse and vibration, sensitivity analyses are performed by the finite element method using Taguchi's scheme. It is shown that the structure of the upper mounting bracket is the most important parameter affecting the vibration characteristics. An optimal design is proposed for a lower tilt type steering column.

The problem of the optimization of the geometry of shafts is formulated in terms of boundary elements. The corresponding nonlinear programming problem is solved by Pshenichny’s Linearization method. The advantages of the boundary element method over the finite element method for optimal design of shafts are discussed, with reference to the applications.

Element Method

Several methods are proposed for improving the slopes stability. We are studying the use of a new technique: concrete lozenges channels. The objective of this technique is to stabilize the slope against water erosion. In addition, it makes it possible to combine both mechanical protection with concrete lozenges channels and protection by plant engineering techniques with plants adapted to the area. The present study is part of the continuation of a parametric study whose purpose was to define the optimal design of concrete lozenges channels. Using the finite element method, the purpose is to study the geotechnical stability of a slope stabilized by said lozenges and to define their constructive arrangements.
