摘要
针对履带车辆在积雪路面的牵引力较差的问题,提出了将北极熊熊爪作为仿生对象,设计出具有较好通过性的仿生履带板.通过理论分析和有限元分析对履带板的牵引力进行计算,建立了履带板积雪路面的力学模型.对不同形式的履带板在积雪路面上的通过性进行分析,并对履带板设计进行了优化.结果表明,影响履带板在积雪路面通过性的主要因素是履刺高度和履带节距,其他因素对履带板的通过性影响较小.
Aiming at the problem of poor traction with tracked vehicles on snow-covered roads,polar bear claws were used as bionic object,and the bionic track shoes with better passability was designed.The traction force of track shoes was calculated by theoretical analysis and finite element analysis,and the mechanical model for track shoes and snow-covered roads was established.The finite element analysis was carried out for the passability of different track shoes on snow-covered roads,and the design of track shoes was optimized.The results show that the main factors affecting the passability of track shoes on the snow-covered roads are track grouser height and track shoe length,while other factors have smaller impact on the passability of track shoes.
