Abstract

This study presents a simple method for balancing a slider-crank mechanism which is applied to a new system. A counterweight is designed and located on the crank link to solve the vibration of slider-crank mechanism. The calculation of counterweight design is proposed to balance the single and double slider-crank mechanisms which are exploited to develop the fast scanning module of scanning acoustic microscopy (SAM) system. Based on the ultrasound characteristics, SAM system can provide the internal image with high resolution up to several tens of micrometers. Following that, the counterweight is optimized to minimize the shaking force acting on the ground frame, resulting in vibration reduction of the SAM system. The equations of shaking force are defined, which are simulated to find out the shape and size of suitable counterweight. Based on the simulation results, counterweights were designed and fabricated, which were used for single and double slider-crank mechanisms of two SAM systems. By interpreting the scanning images provided by SAM systems, the dimensions of specimen are measured at minimum and maximum values that are used to validate the counterweight calculation. Finally, the design process flowchart of counterweight is proposed for balancing slider-crank mechanism, which can be used to extend the mechanism application in many fields.

摘要

本研究提出了一种用于平衡应用于新系统的曲柄滑块机构的简单方法。设计了一个配重并将其放置在曲柄连杆上，以解决曲柄滑块机构的振动问题。提出了配重设计的计算方法，以平衡用于开发扫描声学显微镜（SAM）系统快速扫描模块的单曲柄滑块机构和双曲柄滑块机构。基于超声特性，SAM系统能够提供高达几十微米的高分辨率内部图像。在此基础上，对配重进行优化，以最小化作用在地面框架上的摇动力，从而降低SAM系统的振动。定义了摇动力方程，并通过模拟来找出合适配重的形状和尺寸。根据模拟结果，设计并制造了配重，用于两个SAM系统的单曲柄滑块机构和双曲柄滑块机构。通过解读SAM系统提供的扫描图像，测量样品的尺寸最小值和最大值，用于验证配重计算。最后，提出了用于平衡曲柄滑块机构的配重设计流程图，可用于扩展该机构在许多领域的应用。
