Abstract
With the aid of multidomain modeling method, the vibration of a high-speed punching press was modeled and predicted, and the influence of the installation of foundation, as well as the shape and size parameters of the foundation on the vibration of the punching press, is discussed. The rectangular foundation size with the best effect of vibration reduction under the premise of saving the installation area was obtained. The validity of the multidomain model of the high-speed punching press with the foundation for vibration reduction is verified, by comparing the simulation results with the experimental results.
Highlights
For the continuous improvement of the production efficiency demand of enterprises, the stamping speed and the mechanism inertia force of high-speed punching press gradually increase [1], resulting in serious vibration among the high-speed punching pressing, reducing the stamping quality [2]
Even very slight vibration of the punching press would lead to forming defects during the stamping process; the vibration problem would pose a great threat to the accuracy and service life of the punching press and stamping die and bring vibration and noise pollution to the working environment of stamping workshop and the living environment around the factory
According to the disciplines and theories involved in each part, complex electromechanical products can be divided into different subsystems, such as mechanical system, control system, and electronic system. e vibration problem of punching press system is closely related to the mechanical, foundation, control, electronic, hydraulic, and other subsystems of its organic whole
Summary
For the continuous improvement of the production efficiency demand of enterprises, the stamping speed and the mechanism inertia force of high-speed punching press gradually increase [1], resulting in serious vibration among the high-speed punching pressing, reducing the stamping quality [2]. Based on the numerical simulation of the working performance and operating condition of the punching press, the adjustment of the structure and size parameters of the foundation could be carried out according to the simulation results; the vibration problem of the punching press can be reduced. Multidomain modeling method is a simulation study which combines different disciplines theory and models in the same simulation environment and considers the influence of each domain model parameter on the whole system It can greatly improve the simulation efficiency and avoid the numerical integration error caused by the information exchange between the models established by professional software in different fields [11, 12]. On basis of the multidomain modeling and simulation, influence of the installation of foundation system on vibration reduction effect was studied, and the influence law of block shape and size parameter of the foundation on vibration reduction effect was explored
