Aiming at the complex modal characteristic of the frame of the light electric sanitation vehicle under various working conditions, the finite element method is used to study the natural frequency and modal shape cloud diagram. Based on the frame model established in the three-dimensional software, the model characteristic is analyzed, the natural frequency and modal shape of the first five orders of mode are obtained, and their influences on vehicle travel are analyzed. The frame is improved, and the influence of the improved frame on the natural frequency and modal shape are analyzed. The results show that the bending and torsion resistance of the improved frame is ameliorated. Compared with the torsion resistance, the bending resistance of the frame is much ameliorated, which lays a foundation for the relative experiment, dynamics analysis and structural improvement of the frame.

In spite of the fact that investigation into the plan of action has gotten expanding consideration, few examinations have so far been led on plan of action advancement in a global setting. The reason for the examination is to recognize diﬀerent examples of plan of action development which empowers worldwide retailers to reconstruct their center business rationale in new host nations. Based on looking into the plan of action changes of 15 universal retailers from different home nations to one single host nation (China), our investigation gives an inside and out comprehension of plan of action development with regards to global business. By taking a gander at the ﬁrms abilities in revamping their center rationale in the setting of a host nation, we uncover six courses of retail plan of action advancement. Using the focal point of authoritative learning hypothesis and internationalization, we distinguish three examples of asset arrangement by universal organizations during the time spent creating plan of action developments. Our investigation, thus the, gives experiences and direction to multinational organizations when all is said in done, universal retailers specifically, with respect to how to effectively adjust their plan of action from home nation to have nation.
