China's lotus root industry holds a dominant position in the international market. Given that the rigid chassis of traditional agricultural machinery fails to meet the requirements for stability, trafficability, and adaptability, this study designed a variable triangular track chassis to improve the passability and stability of the harvester in soft and high water content lotus root fields. By analyzing the working conditions of the lotus root field and the force characteristics of the chassis, key parameters such as ground contact pressure of the track, traction force, and power were determined. The overall structure was optimized by using modular design and lightweight aluminum alloy material (ZL303). A three-dimensional model was established using SolidWorks, and finite element analysis was conducted on the drive wheel, variable device, and load-bearing components based on ANSYS Workbench, including stress distribution, fatigue safety margin, and modal characteristics. The simulation results show that when the total mass is 1.1 t and the maximum speed is 15 km/h, the maximum stress of the drive wheel is 44.05 MPa, the fatigue safety factor of key components is all higher than 2.4, and the lowest natural frequency is 323.3 Hz, effectively avoiding resonance with the vibration frequency (50-300 Hz) of auxiliary equipment. In addition, by hydraulically adjusting the track tension (400-2 000 N) and the variable track gauge mechanism, the chassis has a vertical obstacle crossing ability of 300 mm and water depth adaptability of 0.4 m. The whole machine adopts redundant design and modular maintenance system, effectively solving problems such as insufficient system integration, low energy efficiency, and high manufacturing costs in existing technologies. The chassis achieves a load-to-weight ratio of 54.5% when fully loaded, with a center of gravity height controlled below 420 mm. The overturning moment safety factor meets the requirements of GB/T19930-2005 standard, and it reserves 3 sets of power output interfaces and 4 standardized mounting bases, supporting rapid replacement of multi-functional agricultural operation devices, providing a reliable platform for the development of intelligent agricultural machinery equipment.

我国莲藕产业在国际市场占据主导地位,但莲藕采收机械化率较低。传统农机刚性底盘难以满足稳定性、通过性与适应性要求。针对这一问题,研究设计了一种可变式三角履带底盘,以提升采收机在复杂藕田环境中的作业性能。通过分析藕田工况及底盘受力特性,确定了履带接地比压、牵引力、功率等关键参数,采用模块化设计结合ZL303铝合金材料优化整机结构,实现减重与成本控制。利用SolidWorks建立三维模型,基于ANSYS Workbench对驱动轮、可变装置及承重部件进行有限元分析,涵盖应力分布、疲劳安全裕度及模态特性等关键指标。仿真结果表明:当整机满载总质量1.1 t、最高速度15 km/h时,驱动轮最大应力为44.05 MPa,关键部件疲劳安全系数均高于2.4,最低固有频率为323.3Hz,可有效避免与附加设备振动频率(50~300 Hz)产生共振。通过液压系统动态调节履带张紧力(400~2 000 N)和可变轨距机构,底盘具备300 mm垂直越障能力及0.4 m水深适应性。整机采用冗余设计与模块化维修体系,有效解决了现有技术系统集成度不足、能量效率偏低、制造成本较高等问题。该底盘满载时有效载荷比达54.5%,重心高度控制在420 mm以下,倾覆力矩安全系数满足GB/T19930-2005标准要求,且预留3组动力输出接口与4个标准化安装基座,支持多功能农业作业装置快速换装,为智能农机装备开发提供了可靠平台。

我国莲藕产业在国际市场占据主导地位,但莲藕采收机械化率较低。传统农机刚性底盘难以满足稳定性、通过性与适应性要求。针对这一问题,研究设计了一种可变式三角履带底盘,以提升采收机在复杂藕田环境中的作业性能。通过分析藕田工况及底盘受力特性,确定了履带接地比压、牵引力、功率等关键参数,采用模块化设计结合ZL303铝合金材料优化整机结构,实现减重与成本控制。利用SolidWorks建立三维模型,基于ANSYS Workbench对驱动轮、可变装置及承重部件进行有限元分析,涵盖应力分布、疲劳安全裕度及模态特性等关键指标。仿真结果表明:当整机满载总质量1.1 t、最高速度15 km/h时,驱动轮最大应力为44.05 MPa,关键部件疲劳安全系数均高于2.4,最低固有频率为323.3Hz,可有效避免与附加设备振动频率(50~300 Hz)产生共振。通过液压系统动态调节履带张紧力(400~2 000 N)和可变轨距机构,底盘具备300 mm垂直越障能力及0.4 m水深适应性。整机采用冗余设计与模块化维修体系,有效解决了现有技术系统集成度不足、能量效率偏低、制造成本较高等问题。该底盘满载时有效载荷比达54.5%,重心高度控制在420 mm以下,倾覆力矩安全系数满足GB/T19930-2005标准要求,且预留3组动力输出接口与4个标准化安装基座,支持多功能农业作业装置快速换装,为智能农机装备开发提供了可靠平台。

China's lotus root industry holds a dominant position in the international market. Given that the rigid chassis of traditional agricultural machinery fails to meet the requirements for stability, trafficability, and adaptability, this study designed a variable triangular track chassis to improve the passability and stability of the harvester in soft and high water content lotus root fields. By analyzing the working conditions of the lotus root field and the force characteristics of the chassis, key parameters such as ground contact pressure of the track, traction force, and power were determined. The overall structure was optimized by using modular design and lightweight aluminum alloy material (ZL303). A three-dimensional model was established using SolidWorks, and finite element analysis was conducted on the drive wheel, variable device, and load-bearing components based on ANSYS Workbench, including stress distribution, fatigue safety margin, and modal characteristics. The simulation results show that when the total mass is 1.1 t and the maximum speed is 15 km/h, the maximum stress of the drive wheel is 44.05 MPa, the fatigue safety factor of key components is all higher than 2.4, and the lowest natural frequency is 323.3 Hz, effectively avoiding resonance with the vibration frequency (50-300 Hz) of auxiliary equipment. In addition, by hydraulically adjusting the track tension (400-2 000 N) and the variable track gauge mechanism, the chassis has a vertical obstacle crossing ability of 300 mm and water depth adaptability of 0.4 m. The whole machine adopts redundant design and modular maintenance system, effectively solving problems such as insufficient system integration, low energy efficiency, and high manufacturing costs in existing technologies. The chassis achieves a load-to-weight ratio of 54.5% when fully loaded, with a center of gravity height controlled below 420 mm. The overturning moment safety factor meets the requirements of GB/T19930-2005 standard, and it reserves 3 sets of power output interfaces and 4 standardized mounting bases, supporting rapid replacement of multi-functional agricultural operation devices, providing a reliable platform for the development of intelligent agricultural machinery equipment.
