[CN 201810965071.3] Dynamic Analysis Method of Eight-link Mechanical Press


[CN 201810965071.3] Dynamic Analysis Method of Eight-link Mechanical Press Title: Dynamic Analysis Method of Eight-link Mechanical Press Application Number: CN 201810965071.3 Applicant: Zhejiang University Application Date: 2018-8-23 Patent Type: Invention Application The present invention provides a dynamic analysis method of eight-link mechanical press, including the following steps: simplifying the transmission mechanism model; The force analysis of each rod of the transmission mechanism is carried out to obtain the force of each rod; according to the force situation of each rod, the virtual work equation is listed by using the virtual work principle. The kinematic parameters and press tonnage information are brought into the virtual work equation and solved to obtain the crank torque solution curve. According to the simulation processing of the three-dimensional model of the transmission mechanism, the crank torque simulation curve is obtained. Verify whether the crank torque solution curve is consistent with the simulation curve. The invention uses the principle of virtual work to obtain the crank torque by dynamic analysis, the solution is simple, and the calculation efficiency is improved.
