The invention discloses a vibration system for simulating complex excitation in a sugarcane field. The vibration system comprises a vibration platform, a proportional directional valve, a road spectrum input module and a control unit. The vibration platform comprises a lower bearing plate; an upper bearing plate, disposed above the lower bearing plate and allowed to swing in all directions by arranging an elastic mechanism between the upper and lower bearing plates; and two vibration hydraulic cylinders, piston rods of which abut against the bottom of one side of the upper bearing plate respectively. The two vibration hydraulic cylinders are connected with a power system through the proportional directional valve. The control unit is connected separately with the proportional directional valve and the road spectrum input module, and is used for receiving a sugarcane field road spectrum signal and controlling the opening degree and direction of the proportional direction valve based on the sugarcane field road spectrum signal so as to drive the swinging amplitude and direction of the upper bearing plate. The invention is used for simulating the complex road excitation in the sugarcane field and for doing vibration test research on massive test pieces such as a sugarcane harvester gantry, and harvester research and development costs are reduced.
Description
technical field [0001] The invention relates to the field of simulating the excitation of the sugarcane field, in particular to a vibration system for simulating the complex excitation of the sugarcane field. Background technique [0002] The vibration test bench is to simulate the various environments that the product encounters during the manufacturing, assembly, transportation, and use execution stages, and is used to identify whether the product can withstand environmental vibration. It is suitable for electronics, electromechanical, optoelectronics, automobiles, toys, etc. Research, development, quality control and manufacturing in various industries. [0003] The comprehensive competitiveness of the sugar industry in various regions of China is quite low, and it has to bear the huge impact of other WTO sugar producing countries on it. The reason is mainly due to the high cost of sugarcane production and the low level of mechanization. In particular, the important link...
