摘要
【目的】针对山地竹子砍伐后运输下山困难,现行简易索式机械设备效果不稳定,运输跑车续航能力不足,安全得不到保障等问题,设计了一种竹材索道集材跑车运输系统,以实现竹材下山安全、高效运输。【方法】对竹材资源丰富的福建、湖南等竹林场进行调研,确定了竹材索道集材跑车运输系统基本设计参数,设计了悬索和跑车整体功能、尺寸及关键部件,对跑车主要承载部件进行了有限元分析,校核了跑车强度刚度;利用ADAMS软件对索道-跑车系统进行耦合振动分析,确定索道运输竹材过程的主要影响因素。选取运输速度、跑车与竹材总质量、索道倾斜角为考察因素,以跑车运输竹材安全性和效率综合评分为指标,开展Box-Behnken仿真试验,求解优化参数组合。【结果】二次回归正交旋转组合试验结果表明:三因素对跑车运输安全性和效率的影响从大到小依次为索道倾斜角、运输速度、跑车与竹材总质量。当运输速度为3.95 m·s^(−1)、跑车与竹材总质量为576.67 kg,索道倾斜角为17.09°时,运输安全性和效率综合达到最佳。【结论】当承载索倾斜角为16.50°~20.40°、运输速度为3.00~4.00 m·s^(−1)、跑车与竹材总质量为420.00~580.00 kg时,运输安全性和运输效率较好,可在竹林索道集材运输作业的同时充电蓄能、竹材安全高效运输下山。
[Objective]In response to the difficulties in transporting bamboo down the mountain after logging,the unstable effect of current simple cable type mechanical equipment,the insufficient endurance of transportation sports cars,and the lack of safety assurance,this study aims to design a bamboo cableway skidding sports car transportation system,so as to achieve safe and efficient transportation of bamboo down the mountain.[Method]Through research on bamboo forest farms in Fujian,Hunan Provinces with abundant bamboo resources,the basic design parameters of the bamboo cableway skidding and sports car transportation system were determined.The overall functions,dimensions,and key components of the suspension cable and sports car were designed.The main load-bearing components of the sports car were analyzed by finite element analysis,and the strength and stiffness of the sports car were verified.The coupling vibration of cableway sports car system was analyzed by ADAMS software,and the main influencing factors in transporting bamboo by cableway were determined.Taking transportation speed,the total weight of sports cars and bamboo,and the inclination angle of the cableway as evaluation factors,and comprehensive evaluation of the safety and efficiency of sports car transportation of bamboo as indicators,Box-Behnken simulation experiments were conducted to optimize parameter combination.[Result]The results of the quadratic regression orthogonal rotation combination experiment indicated that the three factors which had significant impact on the safety and efficiency of sports car transportation in descending order were cableway inclination angle,transportation speed,and total weight of sports car and bamboo.When the transportation speed was 3.95 m·s^(−1),the total weight of the sports car and bamboo was 576.67 kg,and the inclination angle of the cableway was 17.09°,the comprehensive transportation safety and efficiency reached the best.[Conclusion]The transportation safety and efficiency are good when the inclination ang
