摘要
利用理论力学和材料力学知识,对履带式起重机接地比压的计算建立物理模型和数学模型,通过MATLAB数学计算模块对数学模型进行可视化计算,用图形表达出履带式起重机接地比压与α(主臂和履带之间夹角)之间的关系,并求出履带式起重机最大接地比压,为道路铺设水泥混凝土提供依据。
Base on the knowledge of theoretical mechanics and material mechanics,this paper builds up the mathematical model of crawler crane＇s contact pressure,and uses the module of MATLAB to visualization calculation,then expresses the relation of the contact pressure of crawler crane to a which is the angel between the main jib and the crawler in the horizontal plane. Finally the paper calculates the maximal contact pressure of crawler crane,provides gist for laying down cement concrete on road.
