Abstract


Balancing Machine swing frame vibration system is the main part of the balancing machine , its design is the central issue of balancing machine mechanical structure design , one of the key issues in determining the balance machine performance . This task is to design a the pendulum frame structure of the the static even separation characteristics of a new type of vertical balancing machines and high precision dynamic unbalance measurement , this innovative design , on the structure of the swing frame . Firstly, the establishment of a mathematical model of the general vertical balancing machines . Detailed analysis of the vibration characteristics of vertical balancing machines ; discuss the relationship between the relationship of the center position and operating frequency of the system vibration , static even separation characteristics and operating frequency . Analysis derived from a variety of vertical balancing machine translational natural frequency and twist the value of the natural frequency of the requirement to lay the foundation for the design of the subsequent new vertical balancing machines . To achieve effective separation of unbalance and couple unbalance , swing frame structure design a new type of hard bearing vertical balancing machines and its vibrational structure analysis . As the new swing frame structure uses the spring plate and the cross structure of the spring rod , and the use of dual sensor perpendicular to each other are arranged at the measuring point , such a novel vertical balancing machine can be effectively separated static unbalance and couple unbalance , both minimal impact on each other . Mechanical analysis of different cross-sectional shape of the rod vibration and vibration beam obtained its vibration type equations , and analyze the impact of vibration parameters , key geometry on the vibration characteristics of the dynamic balance . The paper also analyzes the belt drive , bearing balancing measuring system error . New vibrational structure of vertical balancing machines to manufacture a prototype experimental verification from static even separation characteristics . This paper developed a new type of vertical balancing machines , effective separation of the workpiece static unbalance and couple unbalance can be more precise understanding of the quality characteristics of the workpiece . It can be met , the the new vertical balancing machines will get a wide range of applications of vertical balancing machine , which is of great significance .
