竹材切割试验台的设计
|
摘要
为解决我国目前缺乏竹材切割机械设备而导致的竹材采伐困难、成本较高等问题,研发出一种基于往复锯锯切方式的竹材切割测试试验台,其为研制竹材切割机械提供了理论依据及试验基础。试验台主要由液压动力系统、切割系统、数据采集系统及机架等组成,可在不同切割方式、刀刃角、切割速度、进给速度的工况下针对物理力学特性和结构特征不同的竹材进行切割测试和数据采集,分析研究不同切割工况下切割阻力、进给力的变化规律以及建立相应数学模型,为竹材切割机械设计提供数据支撑。
In order to solve the problem that bamboo cutting is difficult and costly due to the lack of bamboo cutting machinery and equipment in China,a bamboo cutting test bench based on reciprocating saw sawing method has been developed which can provide a theoretical basis and test basis for the research and development of bamboo cutting machinery. The test bench is mainly composed of a hydraulic power system,a cutting system,a data acquisition system and a rack,able to conduct cutting testing and data collection for bamboo with different physical and mechanical characteristics and structural characteristics under different cutting method,blade angle,cutting speed and feeding speed conditions,analyze and study the variation rule of cutting force under different cutting conditions and establish its mathematical model,thereby providing a data support for the design of bamboo cutting equipment.
