Influence of mounting and producing imperfections on kinematical properties of mechanism

Abstract

The paper deals with a kinematic analysis of a truck shifting mechanism and usage of sensitivity analysis. The aim of the work is to optimize the trajectory of a shifting lever hand-grip in order to obtain an acceptable ergonomic trajectory. Mathematical surrogate of the shifting mechanism has been constructed to investigate important mechanism features. Sensitivity analyses have been provided in order to identify the critical dimensions the change of which can cause a distortion of the trajectory shape. The analyses have identified problematic parts and new structure concepts have been based on this knowledge.
