Crane Shaking Platform Design, Bixing Yan, Andrea Vacca
The Summer Undergraduate Research Fellowship (SURF) Symposium
Most of the control methodology of Mobile hydraulic crane is not as energy efficient as people think or want, and the desire to innovate novel, energy-efficient control strategy is the target of most hydraulic experts. To develop or test the control method under real road and off-road conditions, a platform that could simulate the movement and vibration of the crane truck is desired. To design and build the multi-operation platform, a design process includes brain storming, design selection, FEA (Fundamental Element Analysis), mechanical sizing, hydraulic sizing and Bill of Material is required and preferred. After going through all the steps …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Displacement Controlled (DC) hydraulics system is booming recently due to its high efficiency and accurate controllability, while the surplus numbers of pumps restrains its further development. DC pump switch technique is a promising application to reduce the number of pumps as well as the cost products to promote DC hydraulics technique. It is necessary to support an innovative DC hydraulic pump switching system with a controller which would allow rapid and accurate estimation and adaptation for all the parameters, like pressures and velocities, in the system. Dynamics and Hydraulics characteristics have initially been investigated for a simplified DC pump switching …
