| At present, the natural disasters which are common all over the world,due to disorderlyspot and hostile environment most bigger mechanical could not get close to the rescue site towork in many emergency rescue in the process. In many cases, depend on human which whocarry some special human hydraulic rescue tools to rescue on the scene still. Therefore, in aview of this practical problem, in need to study designing a new type of small multi-functionJiuYuanChe.In order to reflect the multi-function characteristic of JiuYuanChe, it put into use ageneral quick change device in its structure (hereinafter referred to as general connector),meanwhile which throw light on its design principle and general connector structure theory bythe numbers. According to the actual working condition and working in the size of theresistance and force analysis the paper designs the concrete structure size of the Generalconnectors and optimizes in terms of structure. Using a3d software which is Pro/E to modelfor the general connectors, which draws clear considerable specific three-dimensionalstructure, then through among software interface, take its model into finite element analysissoftware Ansys. Adding load after Simulation of the actual working condition, it is get to aresult that The maximum stress have in selecting a material within the scope of the elasticchanges through analysis of the general connector calculated overall deformation diagram andstress strain cloud, so it is defined that the general design of the connector is reasonable.JiuYuanChe multi-function haves complex structure and more working parts, whichoften works in bad environment, its each component and the movement works in theimplementation without restriction without effect. Therefore, in this paper the designJiuYuanChe adopts full hydraulic pressure system driver forms, it is need to develop thehydraulic system diagram to the job description. Also, it makes a selection of calculation formain actuators according to the actual loading and the changes of work resistance, andcalculate output loading of the various hydraulic actuators, determine the specific parameters.Based on the simulation software AMEsim established JiuYuanChe full hydraulic pressuresystem model, through the parameters Settings with the performance simulation analysis. Thesimulation results show that the JiuYuanChe hydraulic executive parts are individually or working at the same time, and according to the variation of the external load to automaticallyadjust to the size of the displacement, and can meet the design requirements of the maximumload.The multifunctional JiuYuanChe can satisfy the design requirement and the originaltarget, can be in complex rescue site performance multi-usage the characteristics of this toenhance our country’s rescue ability to have the important meaning. |
