About The Customer
Andron Handling Ltd. is a U.K. based company that specializes in the design of bespoke mechanical equipment. Most of their systems are one-off and are designed for a particular application. With mechanical, electrical, ergonomic, and control system expertise, Andron is able to take on any handling requirement. They are currently developing a bespoke handler for a major automotive supplier. The handler is designed to transfer wheel sets from a conveyor system to delivery pallets with tight space constraints. A pneumatic clamping system is used to grip up to four wheels at a time, allowing rotation of the wheels while clamped.
The Challenge
Andron Handling Ltd., a UK-based company specializing in the design of bespoke mechanical equipment, was developing a custom handler for a major automotive supplier. The handler was designed to transfer wheel sets from a conveyor system to delivery pallets within tight space constraints. A pneumatic clamping system was used to grip up to four wheels at a time, allowing rotation of the wheels while clamped. The challenge was to assess the strength of the welded fabrication and vertical clamping arms for both lifting and clamping loads. In previous analyses of this type, Andron would have removed the wheels from the model and applied reaction forces at the bottom of each of the clamp arms. However, for this project, they needed a different approach that would not have been possible with previous FEA toolsets.
The Solution
Andron used Altair SimSolid to model the entire assembly. Clamping forces were simulated by applying a force to each of the four piston rods and a matching reaction to each cylinder body. Sliding connections were applied to the piston and linear bearings to allow this force to be transferred to rigid bodies simulating the wheels. No special preparation of the model was required; the analysis included small components such as circlips and fasteners. The only modifications from SimSolid's default settings were to use increased quality for automatic contact detection, adjust a few of the resulting contact conditions to simulate the sliding of the pneumatic cylinder and linear bearings, and set the wheels models as rigid bodies in order to assign a fixed mass. The entire process, including all setup/preparation and fixing some errors in the CAD model, took only 1.5 hours.

Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).
