摘　　要：文中依据机械原理,设计了一种由棘轮间歇机构与平行四边形传动机构组成的新型宠物自主进食器,详细介绍了结构方案设计过程和工作原理,并采用UG软件进行多体动力学仿真验证和分析。通过仿真解算方案的求解结果,可以直观了解工作进程中运动和力的传递与转换,并由仿真曲线分析重要部件的位移、速度和力等动力学参数,对零部件强度进行校核,保证进食器具有足够的承载能力,通过实例验证了机构设计的合理性与可行性,为后续生产加工奠定基础。In this article,according to the mechanical principle,a new pet autonomous feeder is designed,which is composed of a ratchet intermittent mechanism and a parallelogram transmission mechanism.The feeder’s structure design and working principle are introduced in detail,and the UG software is used for multi-body dynamic simulation,verification and analysis.Both transfer and transformation of the motion and the force when the feeder is in operation are shown clearly through the solution results.The dynamic parameters such as displacement,velocity and force of the important components are analyzed by means of the simulation curves,and their strength is checked,so as to ensure that the feeder has ideal bearing capacity.A range of design examples have verified that this mechanism is rational and feasible,which lays a solid foundation for subsequent production and processing.
