摘要

针对当前某矿用防爆胶轮车质量较大及车架局部刚性较弱的问题

通过HyperWorks的静、动态尺寸优化分析确定出车架各区域钢板的理想厚度

并依据动、静态安全系数对车架模型的钢板厚度作了减薄处理.修改后的模型经ANSYS分析显示前车架前端区域出现了应力集中现象

变形超出设计要求.结合车架的模态分析结果

发现变形较大的原因为前车架前端横向刚度较弱.通过在车架前端局部增加两横梁

重新分析后

结果理想

能够达到车架的设计要求.经优化后

车架总质量减轻了18.27%

车架的约束模态频率相比原结构有较大的增加.

Abstract

The frame of mine explosion-proof rubber-tyred vehicle was weak but with heavy weight

through static and dynamic size optimization an alysis by HyperWorks

and the ideal thickness of the regional steel plate of the frame was determined;then

the steel plate thickness of the frame model was th inned according to the dynamic and static safety factor.By analysing the modifi ed model

the result shows that the front area of the front frame appears stress concentration

and the deformation is beyond the design requirements.Frame mod el analysis results show that the reason of large deformation is the weak latera l stiffness of the front of the front frame.By adding two beams in the regional front of the frame

the reanalysis results were satisfactory and could achieve the design requirements of the frame.Based on the size optimization and structu re improvement

the frame weight is reduced by 18.27%

and the constrained mode frequency of the frame has greatly increased comparing to the original model.
