SAMHOOR speed presses balancing mechanism optimization

    SAMHOOR optimization design is the optimization theory and computer technology in the field of design, provide an important mechanism to optimize scientific design method for engineering design Ba exhibition design is an important direction of modern mechanism design, it is built on the theory of mathematical programming based on the use of computer technology, the optimal design objective function according to some guidelines, and to consider the case of constraints, to seek optimal solutions agencies. Optimization design includes two aspects: the structure of the preferred issues and optimization problems in parameter structure determined under.

    The purpose of high-speed presses balancing mechanism to optimize the design of the program is to raise the static and dynamic characteristics of Gao punch, thereby improving performance punch. Optimization design is mainly composed of three elements: optimization variables state quantity and the target function optimization. Optimization tools are optimized statics and dynamics characteristics of two optimization, static optimization is mainly by changing the structure of the form of machine parts, machine parts and components in order to achieve the minimum of stress; and dynamic optimization is to change machine parts The structure to improve its dynamic characteristics from the optimization point of view, the scope of optimization methods have parameters and topology optimization method optimization method, in which the parameter optimization method by setting design variables and state variables, to meet the state variables of the premise, through change the size of the design variables, the objective function of the optimal value,
     When balancing optimization is to satisfy the constraints in the system variables to make the system as much as possible to achieve dynamic balance, even if the objective function to obtain a minimum. Gao optimization method to optimize speed punch balancing device, are based on different presses balancing structures, literature toggle presses against the lower vibration balancing device design proposes a "two-step" of this optimization method 〃 Early estimates based on a multi-objective optimization, resulting in several possible designs. These designs in comparison with the conventional balancing device designed to better results. Literature presents a balanced and comprehensive utilization deputy slider bars to reduce the inertia force balance Gao speed mechanical presses 9 by way of a six-pole structure punch example, using a slider crank rod structure as a balancing device , respectively deputy slider bar system balance and equilibrium studies, analyzes and bar system balancing device with different roles to play in reducing the weight of the vibration. WH balance study showed truss structure reduces system inertia force two extreme positions of about 10%, while the balance of the deputy slider volatility can be reduced moment of inertia. Vice-balance mechanism for the slider, the literature presents a balancing optimization method according to the principle of change parts less, choose the design variables Vice-link high-speed presses and balance slider mass action system, to avoid to punch larger scale changes, and the objective function is to crank inertial force of the body in the longitudinal direction and the height direction. Optimize the use of two methods to achieve dynamic inertial force around and up and down both directions is minimized. In ADSMS, the first mass-balance slider to M6 for optimizing the object to the crankshaft of the body in the vertical direction in order to optimize the dynamic inertia forces Fy goal, in other punch parameters unchanged condition, choose the appropriate balance slip the mass of the second sub-optimal quality of the sub-link of m4 is optimized object, the direction of the crankshaft to the front and rear fuselage dynamic inertial force Fz as the objective function, the value of time to optimize the quality of the balance sliders after the first, by two sub-optimal method, optimized balancing punch than before optimization has achieved good results.
    High-speed presses balancing mechanism studied in this paper optimization program that, according to the second method of optimization, mainly to consider the impact equivalent inertial force Fy and Fz to punch vibration and choose quality and Deputy Vice-link slider as a system variable, quality adjustment by the Deputy Vice-link and the slider, so punch during operation, minimum vibration, even Fy and Fz reached a minimum.
    In ADAMS / View, the mass balance slider m6 defined as Design Varuable, which is a DV1 minimum force Fy measured moving parts of the body in the Y direction as the objective function Objective. ADAMS will automatically generate design studies and optimization of the process of dynamic changes of inertial forces Fy. In the design of the report, when the minimum value of the objective function to take, the corresponding system variable is the optimal results. The same approach to the quality of the second sub-link optimization, and finally determined sub-link quality speaks m4 = 50.71kg, deputy slider quality m6 = 605.3kg. Crankshaft optimized fuselage after the force curve and slider to force the body curve.
