解决PDM 文件高效存储与请求的问题，提出一种基于负载信息的文件读取均衡算法。根据 PDM 文件请求特点，动态获取数据节点负载信息，通过非顺序请求方式读取文件数据块，合理分配用户请求实现数据节点的负载均衡。实验结果表明，低负载状态下该算法效率与默认算法相当，高负载状态下该算法效率提升明显，用户请求文件等待时间缩短，验证了其有效性。

To solve the efficiency problem of product data management files storage and request ,a load balancing algorithm of reading files was presented based on load evaluation .According to characteristics of product data management files request ,the load balancing of data nodes was achieved by dynamically getting load information ,the file data blocks requested by non‐sequen‐tial were read ,therefore reasonably allocating user requests and achieving good load balancing effects .The experimental results indicate that the efficiency of the proposed algorithm is similar to the default algorithm under low load conditions ,but it obviously shortens the waiting time for users under high load conditions ,so it is more efficient .
