【摘要】 建立了四连杆门座起重机变幅机构中齿轮-齿条振动分析数学模型,运用Solidworks软件对臂架系统及其平衡系统、立柱及齿轮-齿条进行三维模型的建立,并将其导入动力学分析软件Adams中,得到齿轮-齿条在变幅过程中的动态啮合力曲线及动态特性。该研究为实现齿轮-齿条动态设计及优化设计提供了一种新的方法。更多还原

【Abstract】 A driving rack mathematic model was proposed for four-link type portal crane.And a 3D-model of the luffing mechanism was created with Solidworks software.Imported in the Adams,dynamic simulation of the rack gearing was conducted.The dynamic meshing force was calculated.The dynamic simulation result provides basic for the rack gearing dynamic design and optimization design.更多还原
