摘要
以某150 t履带起重机的耳板式履带架为例,分别使用2种有限元建模方案进行结构静力分析,对结构强度进行了评定。对比2种建模方案可知,组装模型虽然计算规模大,但可以获得更为准确的分析结果。
With the crawler frame of 150 t crawler crane as an example two finite element modelinS methods are re- spectively used for structural static analysis and evaluation of structural strength. From such two modeling methods, it can be seen that although the assembling model is of large calculation scale, it can work out more accurately analysis result.
