8 筑路机械设计质量(重量)的评价筑路机械总体结构质量(重量)或比质量(比重量)是表示筑路机械技术水平、结构的完善程度和所采用材料质量的一个重要指标.在提高机械技术使用性能指标或保持其值不变的前提下.对减小机械质量的可能性分析仍是人们特别感兴趣的一个问题。在设计阶段,当考虑采用新型结构和应用具有较高强度指标的机械制造新材料时,设计人员应解决减小机械质量的问题,并预测机械质量的减小比率.在比较国外主导公司生产的类似机械和
8 road machinery design quality (weight) of the evaluation Road machinery overall structure of the weight (weight) or than the mass (weight) is a road machinery that level of technology, the degree of structural perfection and the quality of materials used in an important indicator of It is still a matter of particular interest to analyze the possibility of reducing the quality of a machine by increasing or keeping the value of mechanical performance unchanged. During the design phase, designers should address the issue of reducing mechanical quality and predict the rate of reduction in mechanical quality when considering the use of new structures and the application of new materials for machinery with higher strength specifications. In comparison with the production of Similar machinery and
