GERALD ROESSER

MGA Research Corporation, Troy, MI                                                                                      2002 to Present

Hydraulic Durability Group Leader at MGA Research Corporation’s Michigan Operations. Responsible for day-to-day operations of the group and implementation of long-term strategic goals. 

Areas of expertise include:

Vehicle Durability Testing

  • Provide customer equivalent vehicle miles using Multi Axis Shaker Table (MAST) real time vehicle simulation. Engineer tests based on collected road load data to accurately recreate real world driving events and condense years of usage to days of testing. Vibration using Electro Dynamic Shakers also used to generate high frequency events to reproduce resonance and durability issues along with the detection of buzz, squeak, and rattle.

Suspension System Durability Testing  

  • Developed tests and test rigs to validate suspension components from control arms, cradles, torsion bars and knuckles to bushings, springs, and toe links. Multi actuator rigs are used to run block cycles or perform real time road load simulations on the component level. This type of work is commonly referred to as “poke and stroke”.

 Seating Durability Testing

  • Test procedure and methodology development for KUKA robots and pressure mapping systems used for seat comfort studies and Ingress/Egress testing. Works with customers to determine correct course of action in early development to meet strict seats standards.

Vehicle Exhaust System Testing

  • Experience with full exhaust system testing as well as component level. Design test rigs using propane burners to simulate hot exhaust gas while applying fatigue loads or vibration. Developed capability to run thermal shock testing with water quench while simultaneously testing on electro dynamic shakers.

Accelerated Life Cycle and Environmental Conditioning

  • Developed tests to articulate moving parts on products to determine long-term reliability and durability. Tests are conducted at extreme temperatures to realistically reproduce the effects of real time conditions. Pneumatic actuators are used in conjunction with electronics and PLC controllers accelerate life cycles and find failure modes quickly and precisely. Designs tests to replicate problems in the field so they can be repaired in future product iterations.
