Abstract


Construction increasingly narrow space , supporting the weight of the construction equipment requirements with which the lighter the better , smaller is better . Jack as an important part of the construction equipment , the size and weight reduction not only make the work space is reduced, and save the craft materials , but also to facilitate the construction . Therefore , the jack smaller and lighter is the inevitable trend of development . Virtual prototyping technology is a digital design method based on computer simulation model can greatly improve the design quality and shorten the product development cycle , so this introduction of the technology in which the optimization of jack , designed to further improve the YCW250 jack design . YCW250 jack , the topics for study , the first analysis of the structure of the existing YCW250 jack , strength analysis of its basic parts , thereby determining the guiding ideology of jacks lightweight design ; Secondly UG4.0 software to create a physical model , imported into a dynamic simulation software ADAMS model is built , according to the simulation results for the next stage of the finite element analysis calculation parameters and analyze the dynamic characteristics of the working device ; then built using ANSYS software parameters according to the characteristics of the piston and cylinder mold tool APDL language to determine parts finite element model to entity -based unit , given the key parts of the stress and strain distribution through static analysis , seen parts strength surplus , its parameter optimization ; final meet strength conditions , by optimizing the geometry of the key parts of its weight and volume to achieve optimal . The basic building blocks at the same time do not use high-pressure processing of the fuel tank under the premise of the new material and new seals optimized jack so the technical performance indicators are better than before optimization jack , volume and weight has been significantly decrease in the same tonnage of quality indicators with trip jacks close to the level of developed countries , and provide a valuable basis for further study of the optimization of the other parts of the model jack size . YCW250 jack virtual prototyping technology to improve the design of the Model Jack , to avoid a large number of experimental verification process , reduce design costs , improve the design quality and shorten the development cycle .
