DESIGN AND ANALYSIS OF HYDRAULIC CAR LIFTING MACHINE USING CAE TOOLS

Abstract

A hydraulic lift is a mechanical device used for various applications for lifting of the loads to
a height or level. A lift table is defined as a lift used to stack, raise or lower, convey and/or transfer
material between two or more elevations. Conventionally a lift or jack is used for lifting a vehicle to
change a tire, to gain access to go to the underside of the vehicle, to lift the body to appreciable height,
and many other applications also such lifts can be used for various purposes like maintenance and many
material handling operations. The main objective of the devices used for lifting purposes is to make the
table adjustable to a desired height. A lift provides most economic dependable & versatile methods of
lifting loads; it has few moving parts which may only require lubrication. This lift table raises load
smoothly to any desired height. Lift tables may incorporate rotating platforms (manual or powered); tilt
platforms, etc, as a part of the design. Lift design is used because of its ergonomics as compared to other
heavy lifting devices available in the market. The frame is very sturdy & strong enough with increase in
structural integrity. A multiple height lift is made up of two or more leg sets. For this research project,
there are two basic requirements. The first requirement is to design and another is analysis of a model
of a hydraulic lift which is to control the motion of the constructed hydraulic lift, such as following a
track, which consists of straight lines and curves. These systems are done by modeling software’s like
CatiaV5, and analysis is done by Ansys software. It is found that they are facing some problems
regarding hydraulic lift like job to be lifted are heavier which causes more deformations in hydraulic lift
frame checking deformations & stresses induced in it is a major objective of this project.
