【摘要】 某型装甲破障车发动机支架将承受复杂冲击载荷作用,在满足结构总体布局和轻量化设计等技术要求的前提下,支架应具备足够的强度和刚度条件.在发动机支架的重量不增加甚至减小的条件下,利用有限元仿真技术对支架结构强度和刚度条件进行优化设计,以提高其承载能力,并实现轻量化的设计目标.提出的改进设计方案使支架结构在相同工况下的最大应力减小了24%,最大位移减小了66%.更多还原

【Abstract】 The loads acted on the engine bracket of an armored vehicle during working are complicated. Therefore the bracket should be of enough strength and rigidness. Under the condition of the given overall design requirements,an optimized design scheme with respect to the lightweight is proposed and verified by finite element method. The simulation results show that the maximum Mises stress is reduced by 24% and the maximum displacement by 66% in the same load conditions.更多还原
