Özet

Remotelycontrolled hydraulic bottle jack was designed in this study to alleviate thedifficulties encountered during auto servicing that requires certain choice ofelevation. Major components of the hydraulic jack were housed in a metal casingof 220mmx220mmx180mm with 2mm thickness. Curbweight (weight of the car with all fluids and components but without thedriver, passengers, and cargo) of several cars ranging from 1086kg-1970kg were determined using a scale at nearbyautomobile shop. Considering the weight of individual cars that the designedhydraulic jack elevated, the time required to attain upward stroke of thepiston and specific height of elevation was recoded accordingly. The timevaried between 1.2 minutes with specific height of 150 mm and 1.44 minutes withspecific height of 112 mm. Half weight of 1970 kg (985 kg) was used as the loadcase in Finite Element Analysis (FEA) to check the stress deformations,displacement and equivalent strain. Maximum von-mises stress of 8.465x106 N/mm^2 was obtained which is below the yield strength of the jack pistonmaterial. Maximum displacement of 2.999x10-1mm and maximum equivalent strain of 3.56x10-3. Factor of safety waschosen on a scale of 1-10, and the colour chart in the analysis indicated bluecolour in the range of 7-10 throughout the jack assembly. This was anindication that the jack is safe to operate under the aforementionedapplied load. Therefore, adoption of remotelycontrolled hydraulic bottle jack can save time and energy required to elevatevehicles to working height.
