工程机械结构的设计随着时代的进步要考虑的因素越来越多,而传统的设计方法往往就难以应付,如果要把结构设计得尽量合理,那就需要运用现代化的结构优化理论与方法。传统的结构设计,是根据人们的经验和必要的产品借鉴,通过判断去给定设计方案,然后根据方案作力学分析,校核它是否满足设计要求(即安全可行)。在这里有两个问题需要考虑: The design of construction machinery structure with the progress of the times to consider more and more factors, and the traditional design methods are often difficult to cope with, if you want to structure as reasonable as possible, then you need to use modern structural optimization theory and methods. The traditional structure design is based on people’s experience and the necessary product reference, through judging to give a design, and then make a mechanistic analysis according to the program to check whether it meets the design requirements (that is safe and feasible). There are two issues to consider here:
