Stiffness Re-Design and Insert Solutions for the ZBee

Abstract: This thesis presents a systematic approach to solving the problem of large deflections in the ZBee vehicle, proposing feasible insert solutions while reducing weight and increasing efficiency were possible.An experimental study was done on the structural deformations of a sample ZBee floor using highly advanced measuring instruments. Based on this background a finite element model was developed which simulates the experiment to a good level of correlation. Modifications were then carried out on the model to examine different factors which affect the stiffness and hence deflections experienced by the driver. Based on a systematic selection of alternative solution an insert analysis was done which gives initial design parameters for a new insert implementation.To improve the manufacturability and hence cost of the Zbee floor, a new floor design with simpler geometry was analyzed and further developed based on the stiffness properties studied on the old chassis.
