【摘要】 针对设计悬挂机构时用图解法求解出悬挂参数效率低效果不好的问题 ,本文以三点悬挂犁耕机组为例 ,介绍了机械 CAD确定三点悬挂机构参数的方法。该方法以保证入土性能和稳定工作来设计悬挂参数 ,并对相应的性能指标进行校核。在校核油缸提升力时 ,提出了一种新的计算方法 ,可计算出任一位置时的提升力 ,从而可找出最大提升力 ,使校核更准确。根据要满足的不同目标进行优化设计 ,使设计质量有较大的提高。更多还原

【Abstract】 Aiming at the problem of inefficiency in choosin g the parameter of hitch by graph, we present a method for determining the param eter of the three-point mounted mechanism with mechanical CAD, which is based o n the three-point mounted plough group. This way ensures the mechanism’s earth -entering performance and working stability, and the performance guidelines wer e tested. In testing the rifting force of hydro-cylinder, a new calculating met hod was presented, which can calculate the rifting force everywhere and find the maximum. It improved the safety of design greatly. The design quality can be gr eatly improved by optimal design for different targets.更多还原
