This article guarded against explosions the heater to skid the block comprehensive support the structure to carry on the analysis ; found the question which this support structural design exists and has made the corresponding improvement design ; caused to synthesize the support the structure while to satisfy the intensity and rigidity reduced the whole weight ; tends to the optimized design in the material use ; through to synthesizes the support the finite element model to exert the different force of inertia ; obtains under the different load to synthesize the support stress variation rule , thus determine bearing capacity of comprehensive support 摘要本文对防爆加热器撬块综合支架的结构进行了分析,找到该支架结构设计上存在的问题并作了相应的改进设计,使得综合支架的结构在满足强度和刚度的同时减轻了整体的重量,在材料的利用上趋于优化的设计;通过对综合支架的有限元模型施加不同的惯性力,得出不同载荷下综合支架应力变化规律,从而确定出综合支架所能承受的最大惯性力。
