【摘要】 为了减少叉车的振动,以振动功率最小为目标,对叉车动力装置在车架上的支点寻优.把车架简化为三边固定一边自由的模型,运用振动基本理论结合功率流理论对车架模型进行了振动分析,得到了数学模型,并对此板结构进行了动力装置支点位置分析,运用此方法解具体算例,计算结果与ANSYS模拟结果相同,验证了该分析方法的正确性.更多还原

【Abstract】 In order to reduce the vibration of the forklift,the forklift power assembly fulcrum is optimal designed when the minimum vibration power flow used as the goal.First of all,the frame model of one-freedom side-trilateral fixed side is modeling.Using the basic theory of vibration power flow theory analyses the model.Then mathematical model is obtained.After the plate structure is analyzed,the optimization position is gotten.Finally,using this method calculates a concrete example.The calculation is the same as the results with the ANSYS simulation result,which verifies the correctness of the method.更多还原
