Dynamics Simulation And FEA Analysis For Ultra-thin Scissor Lift Based On Virtual Prototyping Technology

In order to meet the small room, wide application of car types and other requirements and reduce development cycle, this paper use virtual prototyping technology for new ultra-thin scissor lift mechanism for design optimization and strength check. It provide the necessary basis for the physical prototype manufacturing.This design goal is determined by analyzing the characteristics of thin Scissor Lift. They are minimum standards on vehicle height required, rated lifting weight to 3 tons and the safety factor for safety mechanism meeting CE certification requirements. Analysis of the structure and the working principle of the ultra-thin scissor lift and completing lift overall structural design and using 3d modeling software Solidworks to establish a thin scissor lift of 3d modelUse ADAMS to create virtual prototype of car lifts and make dynamic simulation. By simulation of descending by lift from heavy-duty, study the relationship between the car lift reaching the minimum height and rotating the sub-gap. Confirmed that the minimum height of the car with the deputy in the gaps about the rotation, solving the problem of minimum standards on vehicle height. After simulation of max force require for cylinder when lift rise up from minimum height, it is found that current design cannot meet the design requirements. Lift mechanism has been optimized for analysis and simulation. By increasing the lifting angle, change the ratio from the arm and boom lift inverted plate, optimizing the structure so that the fuel tank cylinder is no longer in contact with the panel in lowest level rises, effectively improve the necessary cylinder output force. According to CE requirements, on the strength of the worst conditions of the safety component, using ANSYS Workbench software for static strength analysis. Depending on the strength of the parts analysis structural optimization, the optimized lift reach CE requirements and get savings in materials. Through this study, shortening the development cycle of physical prototypes, saving the cost and plays an important role on the final shape of the product.
