重型载重车平衡悬架系统技术提升

由于重型载重车承载力大且使用工况恶劣,导致整车平衡悬架平衡轴总成在使用过程中平衡轴断裂、平衡轴支架产生裂纹等故障频发,严重影响客户正常使用,同时使得售后维修及索赔成本大大增加。文章针对平衡轴总成在使用过程中的失效模式,对重型载重车的平衡悬架系统进行技术提升,在原有技术及结构基础上,设计了一种新结构平衡轴总成,从而大大降低了平衡轴总成故障率,最大程度的提高了平衡轴总成使用寿命。

Ship inspection support system using a product model

 Recently, the significance of ship inspections has been increasingly recognized because sea pollution and safety problems are occurring more and more frequently. However, current ship inspections rely on the experience of the workers. Therefore, it is difficult to understand, and hence to improve, the state of ship inspections. In this paper, ship inspection is directed into three stages (plan, do, and check), and the configurations of a total system to support ship inspections are discussed. A prototype system for the “plan” and “do” stages is developed. This is realized by organizing the information that relates to inspection, and defining data models for damage and inspection states. Then the proposed system is integrated with a shipbuilding computer integrated manufacturing (CIM) system so that the ship's structural information can be used effectively. In addition, functions to calculate the damage-finding probability, and functions to generate information about damage and the inspection state are introduced. Therefore, in the planning stage, as inspector can execute a virtual ship inspection, and then the damage-finding probability of each hull part and oversight areas are calculated automatically. Further, by carrying this system into an inspection, an inspector can generate damage information and inspection information simply and easily. Some examples of the proposed system are shown at the end of the paper. Received: November 12, 2001 / Accepted: January 30, 2002
