摘要
设计一种以单履带为行走机构的山地果园运输车,该山地果园运输车由单履带行走装置、车架、传动装置、动力系统等组成,其主体外形尺寸为1 540mm×600mm×815mm。根据整车质心分析和人机工程学确定车辆的结构和运动参数,并利用Creo建立三维模型,计算出车辆的质心位置。根据车辆的质心位置分析车辆在横向坡面和纵向坡面的稳定性。对该山地果园运输车样机在满载情况下进行不同工作环境的测试,结果表明:设计的山地果园运输车的最大载荷为75kg,具备上10°纵向坡,下30°纵向坡以及通过20°横向坡面和通过各种复杂路面的能力。该运输车能够较好地满足山地果园横向运输要求。
A mountain orchard transport vehicle with single crawler was designed.The main body of that dimension is 1 540 mm×600 mm×815 mm,assembled by a single crawler walking device,frame,transmission,power systems and other equipment.The vehicle centroid analysis and ergonomics were used to determine the structure and movement parameters of vehicle.Creo was operated to build a model to calculate the vehicle’s centroid position.Based on the vehicle’s centroid position,the stability of the vehicle on the lateral and longitudinal slopes was analyzed.With full load,the prototype under different working environment was tested.Results showed that the maximum load capacity was 75 kg,with the ability to go up 10 degrees and go down 30 degrees of the longitudinal slope.It can run across the slope of 20 degrees and run through various complex roads.The vehicle can well meet the requirements of mountain orchard lateral transport.
