| Abstract: | A certain type of heavy truck frame is taken as subject,and a FEA model of the frame was developed with the software ANSYS based on FEM and static/dynamic theory.A modal simulation was done to analyze the frame,so as to get the relationship between its natural frequency and corresponding modes of vibration of different orders.Modal experiment of the truck frame was carried out by a fixed resonator,the method of single point and resonance-multiple points,and relevant response signals were obtained.Comparing ... |
