Abstract
New additive metal powder technologies are increasingly used for various prototypes. Different powder materials can be used for very complex shapes. Water hydraulics needs new technologies and new approaches to enable more frequent use by users. A new shape of housing for a water hydraulic proportional directional control valve was designed. FEM and CFD analyses of the valve housing were performed. Based on the results of the initial numerical analyses, topological optimization of the valve housing was performed. The prototype of the valve was fabricated from non-corrosive Inconel powder using 3D printing process. After machining, the valve was assembled and experimentally validated on the water hydraulic test rig. The new 3D-printed Inconel valve housing is more than 3 times lighter than similar housings of industrial valves.
Highlights
Climate change has become one of the greatest risk factors for humanity in recent decades
There are other components installed on the trolley that were not used in these measurements
After all necessary repairs were made to the valve, we isolated and demonstrated the effects of each of the components that make up a two-stage pressure relief valve with a series of measurements in which we replaced each element individually
Summary
Climate change has become one of the greatest risk factors for humanity in recent decades. Extreme weather and natural disasters have forced societal attitudes to change. Regulations of the UN and the federal government provide motivation for all sectors to further develop their current practices in terms of economic and ecological aspects to combat climate change. Fluid power is an important drive technology when a good controllability of high forces or high torques is required. Fluid power can be a very sustainable future technology. There are some aspects that need to be solved to contribute to worldwide climate goals and to satisfy sustainability demands
