The invention relates to the technical field of airship equipment, and discloses a vibration reduction scheme for an airship propulsion device. The device comprises a rigid support, a propulsion apparatus and a vibration reduction unit, the propulsion apparatus is a duct power apparatus or a propeller power apparatus, and the power apparatus can be vectorial or non-vectorial and is driven by a piston engine or a motor; the vibration reduction unit is a passive hydraulic vibration reduction unit, an air spring vibration reduction unit or an active piezoelectric ceramic unit. By means of the vibration reduction scheme, vibration caused by the propulsion apparatus can be effectively reduced, the stress condition of the rigid support and the airship body is optimized, the weight of a connecting portion of the rigid support and the airship body is reduced, and the economical efficiency of the airship is improved. Meanwhile, the service life of the rigid support and the service life of the airship body can be prolonged through reduction of vibration, and the safety and durability of the airship are improved.

    本发明涉及飞艇设备技术领域,公开了一种用于飞艇推进装置的减振方案,包括刚性支撑、推进装置及减振单元,所述的推进装置为涵道动力装置或者螺旋桨动力装置,该动力装置可为矢量或者非矢量的,由活塞发动机或者电机驱动;所述的减振单元为被动式的液压减振单元、空气弹簧减振单元或者主动式的压电陶瓷单元。改减振方案可以有效的降低推进装置引起的振动,优化刚性支撑与飞艇艇体的受力条件,降低刚性支撑及艇体连接部位的重量,提高飞艇经济性。同时,振动的减小可以延长刚性支撑与艇体的使用寿命,提高飞艇的安全性及耐用性。
