| Abstract: | Plate-cone cylindrical reticulated shell is a new type of space structure pattern. Due to bearing reasonable internal force, integral rigidity and good stability, plate-cone cylindrical reticulated shell is regarded as a new structure pattern which has broad development prospect. Adopting subspace iteration method, this paper is concerned with the study on performance of free vibration of plate-cone cylindrical reticulated shell on the basis of finite element. Effects of structure main parameters, such as different span, the ratio of rise to span, the ratio of long-span and lattice size are researched in detail. Based on analysis and calculation of many parameters, rules of free vibration for plate-cone cylindrical reticulated shell are got. The results are valuable in application and engineering design of plate-cone cylindrical reticulated shell. |
