Working principle and simulation of variable linear shaker

Working principle of linear shaker is analyzed when exciting force doesn't act through the center of shaker box,and the concept of variable linear shaker is put forward.It is possible to achieve complex variable linear track of screen without any constrains~() and motion parameter of screen surface is simulated. Conclusions are the following by properly adjusting the relative position between exciting force and mass center of shaker box, and screen surface and mass center of shaker box, it is able to design new linear shaker with greater treating ability than currently linear shaker can be designed. These conclusions can be used to design new linear shaker and rebuild currently linear shaker.
