柜体变形理论研究

用分析法研究了基本柜体和带有搁板与隔板柜体的变形。组成柜子的每个板件刚度，可用实验方法测得，或用计算法求得。如何部件刚度已知，柜体变形可由公式求出。用公式计算的变形量，与实测结果一致。通过理论分析，确定了影响柜体刚度的因素，从而得到增强柜体刚度的措施。例如，尽可能增加搁板和隔板数量；将顶，底板制成箱形结构；在背板四周边胶贴胶合板条，以增加背板刚度；还可制成带前框的柜子，并在角部胶结木块。柜体变形理

THEORETICAL STUDY ON DEFLECTIONOF CABINET BODY

The deflection of the cabinet has directly influence on its using functions.Ifthe rigidity of the cabinet is lower,the door could not open or close correctlyThe rigidity of the cabinet could not meet the requirements of quality specificationin this case.The method of analysis is used to investigate the deflection characteristics of the basic fivesided cabinet which may contain both shelves and partitionsin the paper.The stiffness of the appropriate panels of the cabinets may bemeasured experimentally or calculated by means of the expression. If the rigidityof panels is known,the deflection of the cabinet body can be calculated by meansof the expression. This deflection is the same as the experimental result.The factors affecting the rigidity of the cabinet body can be found with thetheoretical analysis.We can get the method of what increases the rigidity of thecabinet body.For instance,We can increase the number of shelves and partitionsas many as possible.The top and bottom panels can be made into casedstructure.The rear panel can be stiffened by glued the plywood strips onto itsperiphery.We can make the cabinet with a front frame and glue blocks to thecorner.The theoretical study on deflection of the cabinet body could improve thestructure design of the cabinet body.The design calculation not only could savematerials but also meet the demand of the quality.
