工程塑料在工业、农业、国防等各个领域得到广泛的应用。在许多机器、仪表或各种设备中的零件,用塑料代替金属材料在日益增加。设计受力作用或作为基体使用的塑料零件(如壳体、器皿、支承或基座等),或是用塑料零件更换已有设备的某些零件,往往需要有加强肋。其目的是提高零件的强度和刚度。也是为了使结构和用料有较好的合理性。根据使用条件,如何选择有肋塑料零件的截面形式、尺寸大小和肋的数目呢?这里介绍一种较快和简便的计算方法。
Engineering plastics in the industrial, agricultural, national defense and other fields have been widely used. In many machines, meters or various parts of equipment, the use of plastic instead of metal materials is increasing. Reinforcing ribs are often required to design plastic parts (such as housings, utensils, supports or pedestals, etc.) that are used as a base or used as a base, or to replace parts of existing equipment with plastic parts. Its purpose is to improve the strength and rigidity of the part. It is also to make the structure and materials have better rationality. According to the conditions of use, how to choose the ribbed cross-section of plastic parts, size and the number of ribs? Here is a quick and easy calculation method.
