摘要
发动机机体不但承受着燃气爆发压力、旋转及往复惯性力的作用,而且外负载的反扭矩通过台架系统与发动机支承作用于机体。采用有限元结构强度和刚度计算分析的手段,通过一种典型机体故障模式的分析,阐述了在台架试验系统中不同支承形式对机体可靠性试验验证的影响。
The body of engine not only bears the maximum gas force and rotating as well as reciprocating inertia forces, but the reverse torsion with outer load are also act on it via supporting and rig test system, This paper expatiates the reliability test influence in the body of different supporting form by analysis of typical body failure mode.
