DfR of iBooster Gen 2 Valve body by changing the material

Abstract

The iBooster Gen2 is currently commercialized in three different motor versions: size1, size1+ and size2. Each motor size generates a maximum torque which corresponds to a maximum support force required to slowdown the vehicle. In all these configurations the material of the Valve Body is PET50GF. The possibility of future size3 motors leads to a decrease of the system reliability below of the safety requirements. Therefore, the goal of this project is to identify a new plastic material for the Valve Body able to withstand the size 3 load collective of the iBooster Gen2 without changing the geometry of this part.
