Optimisation of shock absorber process parameters using failure mode and effect analysis and genetic algorithm
The various process parameters affecting the quality characteristics of the shock absorber during the process were identified using the Ishikawa diagram and by failure mode and effect analysis. The identified process parameters are welding process parameters (squeeze, heat control, wheel speed, and air pressure), damper sealing process parameters (load, hydraulic pressure, air pressure, and ...
متن کاملNumerical and Analytical Investigation in Radiated Noise by a Shock-Absorber
In this article, the radiated noise by a shock-absorber is studied. This particular shock-absorber is used in a heavy-gauge shearing line in order to stop the cut steel sheets. Three steps are followed to evaluate the propagated sound in the surroundings; first of all, the plate vibration response is specified after the impact. Secondly, the edges of the plate are substituted by a set of the mo...
متن کاملDetermination of Shock Standoff Distance for Wedge at Supersonic Flow
An experimental investigation is conducted to calculate the shock standoff (SSO) distance in front of an acute-angled wedge. For this experimentation, simple water flows channel analysis is carried out. The flow velocity is varied from 13.2 cm/s to 25.5 cm/s increasing in steps of 1 cm/s. A velocity of 13.2 cm/s corresponds to Froude number 1.13 and velocity of 25.5 cm/s to Froude number 1.41. ...
متن کاملCar crash tragedy
A tragic car crash has killed two distinguished British researchers. Dame Anne McLaren and Professor Donald Michie died when their car came off the motorway between Cambridge and London last month. Anne McLaren was a leading geneticist who became the first female official of the Royal Society and Michie was a researcher in artificial intelligence who worked as part of the British codebreaking g...
متن کاملNumerical and Experimental Investigation of the Effect of Different Orientation Angles on Crash Behavior of Composite Hat Shape Energy Absorber
Car body lightening and crashworthiness are two important objectives of car design. Due to their excellent performance, composite materials are extensively used in the car industries. In addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. Hat shape energy absorber is used in car’s doors for side impact protection. The aim of these numerical models and expe...
