Looking for someone with advanced FEA skills to create a model of a simple impact socket wrench having specific material and dimensions properties (supplied), and then simulate an air impact wrench loading on this socket for the purpose of optimizing the mass of the socket for a specific target load. Modeling the load of an impact wrench is not simple and built in features in AutoCAD are not what we want. This is not the same as a static load, hence the need for someone with the advanced knowledge to model this correctly and simulate needed conditions. Details of hammer mass inside the impact wrench are different for every brand and model, so will need to be approximated. We can supply ballpark figures of rotational load and spikes of impact typical to an average model. Resistance to spinning is based on thread friction between bolt and nut and given CoF with no lubricant. Here we can assume full tightness and allow no rotation, however some torque will still be absorbed or transferr...

Project Description: I am looking for a seasoned mechanical engineer to further enhance a dispensing system. The candidate should have experience with gear design, working knowledge of injection molding and experience working with polymer plastics. I am strictly looking for an engineer that have solid experience with mechanical design rather than a drafter. The candidate should also have experience with Solidworks,FEA and solidworks simulation.

The plugin should be able to embedd fluid codes generated into Solidworks flow simulation and the stand-alone application via MS visual studio should call the Solidworks flow assembly and vary different impellers modelled (6 blade Rushton impeller, hydrofoil impeller and a conceptualized impeller) , carry out parametric analysis of simulation of the impeller (fluid height in containing vessel, impeller distance from vessel bottom, various position of impeller and vessel ) and determine the best impeller.that will give a better homogeneity of the fluid to be mixed). The working fluid is a non-Newtonian fluid. Details of dimensions of impeller and containing vessel are available both in doc and sldprt formats.
