【摘要】：为了解决传统的被动式的隔振方法在控制船用柴油机振动时性能上的缺陷,满足人们对船舶振动越来越高的要求,本文设计研制了一款新型的主被动复合隔振器。本文将其设计在传统的被动式的双层被动隔振系统基础之上,增加一个次级力源装置对系统中间质量输出激振力,通过适当的控制算法对次级激振力进行控制,对被控的振动系统输入外部能量,减小系统力的传递率,以达到振动控制的预定目标。主被动复合隔振器主要由上、下两层隔振装置,作为中间质量的中间平台,以及安装在中间平台上的四台惯性式电磁作动器与功率放大器等设备零件组成。本文的研究工作围绕着主被动复合隔振器中惯性式电磁作动器设计和主被动复合隔振器整体结构设计展开,深入分析隔振原理,设计出各部分的零件图,经过加工生产出各个部分的零件,并最终装配成样机。论文的主要工作包括:1、从隔振的基本原理出发,重点探讨两层隔振系统和双层主动控制隔振的系统特性,为主被动复合隔振器的设计提供必要的理论依据。2、完成了惯性式电磁作动器磁路的设计,选用钕铁硼稀土永磁材料作为作动器磁路中的永磁体,选用10#钢作为软磁材料。并使用Ansoft电磁场有限元分析软件详细地分析了轭铁厚度、导磁磁缸厚度和导磁磁缸长度对设计的钕铁硼永久磁铁磁路特性的影响。对惯性式电磁作动器弹簧,风扇的重要组成部件进行了计算。依据仿真与计算的结果,利用AutoCAD软件对惯性式电磁作动器的各个零件进行了详细的设计工作,并用Pro/e建模软件建立了惯性式电磁作动器的二维效果模型。在各个零件加工完成之后,对惯性式电磁作动器进行了了组装工作,并对其性能进行了详细的测试工作。测试结果表明四台惯性式电磁作动器的性能良好,完全可以作为振动主动控制系统的次级激振力。3、确定了肖氏硬度为60～70HS的丁腈橡胶(NBR)作为上下两层隔振橡胶的材料,并根据主被动复合隔振器的尺寸,对上下两层的隔振橡胶组件进行了了设计,并计算出橡胶组件在承载5吨静载力的情况下的变形量,通过理论计算并对比Ansys的计算结果,表明本文的设计的隔振橡胶组件的变形量完全在允许的范围内。最后完成了主被动复合隔振器其他部件的设计,并根据设汁图纸建立了三维立体模型,各个零件加工完成之后,并对主被动复合隔振器进行了组装,为振动主动控制试验做好了充分的前期准备。
[Abstract]:In order to solve the defects of the traditional passive vibration isolation method in controlling the vibration of marine diesel engine and meet the higher and higher requirements of ship vibration, a new type of active and passive composite isolator is designed and developed in this paper. In this paper, it is designed on the basis of the traditional passive double-layer passive vibration isolation system, and a secondary force source device is added to output the excitation force to the intermediate mass of the system, and the secondary excitation force is controlled by the appropriate control algorithm. The external energy is input to the controlled vibration system to reduce the transmission rate of the system force in order to achieve the predetermined goal of vibration control. The active and passive composite isolator is mainly composed of upper and lower two layers of vibration isolator, which is used as the intermediate platform of intermediate mass, as well as four inertial electromagnetic actuators and power amplifiers installed on the intermediate platform. The research work of this paper revolves around the design of inertial electromagnetic actuator and the overall structure design of active and passive composite isolator in active and passive composite isolator. The principle of vibration isolation is deeply analyzed and the part drawings of each part are designed. After processing and production of each part of the parts, and finally assembled into a prototype. The main work of this paper is as follows: 1. Based on the basic principle of vibration isolation, this paper focuses on the characteristics of two-layer vibration isolation system and double-layer active control vibration isolation system, and provides the necessary theoretical basis for the design of passive composite isolator. 2, The design of magnetic circuit of inertia electromagnetic actuator is completed. ND-Fe-B rare earth permanent magnet material is selected as permanent magnet in actuator magnetic circuit and 10 # steel is selected as soft magnetic material. The effects of yoke iron thickness, magnetic cylinder thickness and magnetic cylinder length on the magnetic circuit characteristics of the designed ND-Fe-B permanent magnet are analyzed in detail by using Ansoft electromagnetic field finite element analysis software. The important components of inertia electromagnetic actuator spring and fan are calculated. According to the results of simulation and calculation, the parts of inertial electromagnetic actuator are designed in detail by using AutoCAD software, and the two-dimensional effect model of inertial electromagnetic actuator is established by Pro/e modeling software. After the machining of each part, the inertial electromagnetic actuator is assembled, and its performance is tested in detail. The test results show that the four inertial electromagnetic actuators have good performance and can be used as the secondary excitation force of the active vibration control system. 3, The nitrile rubber (NBR) with Shaw hardness of 60~70HS was determined as the material of the upper and lower two layers of vibration isolation rubber, and according to the size of the active and passive composite isolator, the vibration isolation rubber assembly of the upper and lower layers was designed. The deformation of the rubber assembly under the condition of bearing 5 tons of static load is calculated. Through theoretical calculation and comparison of the calculation results of Ansys, it is shown that the deformation of the vibration isolation rubber assembly designed in this paper is completely within the allowable range. Finally, the design of other components of the active and passive composite isolator is completed, and the three-dimensional model is established according to the juice setting drawings. After the processing of each part, the active and passive composite isolator is assembled. Adequate preparation has been made for the active vibration control test.
