The invention discloses a turboprop engine arrangement method and a vibration reduction system, a turboprop engine is arranged through the vibration reduction system, and the vibration reduction system comprises a front side vibration damper, a front upper vibration damper and a rear side vibration damper which are installed between an aircraft frame and the turboprop engine; a torque compensation device is further arranged on the aircraft frame and connected with the front shock absorber. The turboprop engine arrangement method comprises the step of optimizing a pre-compression method of rubber assemblies in a rear shock absorber, that is, the rear shock absorber comprises a main support assembly, the rubber assemblies comprise the first rubber assembly and the second rubber assembly, and the main support assembly is arranged between the first rubber assembly and the second rubber assembly. A main bolt sequentially penetrates through the middle position of the second rubber assembly, the main support assembly and the middle position of the first rubber assembly and then is locked with a nut, so that the second rubber assembly and the first rubber assembly are tightly pressed on the bottom face and the top face of the main support assembly, and rubber bodies in the second rubber assembly and the first rubber assembly are in a pre-compressed state.
本发明公开一种涡桨发动机布置方法及减振系统,涡桨发动机通过减振系统布置,减振系统包括:安装在飞机框架和涡桨发动机之间的前侧减振器、前上减振器和后侧减振器;在飞机框架上还设置有扭矩补偿装置,扭矩补偿装置与前侧减振器连接;涡桨发动机布置方法包括对后侧减振器中橡胶组件的预压缩方法进行优化,即:后侧减振器包括主支架组件,橡胶组件包括橡胶组件一和橡胶组件二,主支架组件设置在橡胶组件一与橡胶组件二之间,安装时,利用主螺栓依次穿过橡胶组件二的中间位置、主支架组件和橡胶组件一的中间位置后与螺母锁紧,从而将橡胶组件二和橡胶组件一压紧在主支架组件的底面和顶面上,使得橡胶组件二和橡胶组件一中的橡胶体呈预压缩状态。
