Application and development of mechanical dynamics 机械专业(英语论文).docVIP

Application and development of mechanical dynamics Beginning of the 21st century, the development of dexterous manipulator, walking robots, machine tool, removable optical instrument platform, train, automobile active chassis as the representative of the intelligent electronic products will be one goal of Chinas machinery industry. Such mechanical and electrical products with innovative materials, structural lightweight, mobile, intelligent and high, resulting in a material nonlinearity, complex geometric nonlinear dynamics, nonlinear control with lag. These issues will be studied mechanical dynamics in the field of frontier in the early 21st century. First the contents of the mechanical dynamics： Any mechanical, while in the presence of motion, will be subject to the force. In the study Machinery and mechanical force generated by the movement in motion when the mechanical dynamics, and mechanical design and improvement of science from the perspective of the interaction force and movement. Detailed mechanical dynamics research can be divided into the following six: （1）At a known external force, required to have identified the true movement of the inertial parameters of the mechanical system; analysis of interaction between the various components of the mechanical motion; research institutions and balance theory and method of the rotary member; mechanical vibration analysis; and institutional analysis and synthesis, and so on. （2）Analysis of the interaction between the various components of the mechanical movement. Size and variation of the structural design of these forces is deputy campaign, the carrying capacity of supporting and component analysis and the choice of a reasonable basis for lubrication method. After obtaining the mechanical movement of the real force of inertia can be calculated for each member, and then based on Alembert principle determined by statics interaction between components. researching the institutional balance and the
