轨道式门座起重机动态测试设计与范例分析

Dynamic Test Design and Sample Analysis for Orbital Portal Crane

为了获取门座起重机在实际工况中对金属结构产生的动载荷,文中在对轨道式门座起重机载荷分析的前提下,根据测试对象的结构特点以及测试仪器的精度,设计了动态应力测试的试验方法;同时结合实例对测试结果进行分析,总结测试方案,提出一些关于港口机械动态测试的建议,为以后同类测试提供参考。

Obtaining the dynamic response of portal crane structure during works at the realistic operation, test method of dynamic stress is devised by analyzing the loads of crane and the property of structure and the precision of test apparatus in this paper. Then the test results were analyzed and verified by an example. The project is summed up, some advices were brought up in the dynamic test of portal mechanism for the future work.
