除雪铲分段式避障结构设计与铲刃分析

Design for Segmented Obstacle Avoidance Structure of Snow Shovel and Analysis on the Shovel Blade

为有效地避免清洗/除雪一体化车在遇到小型障碍物时出现的遗雪量增多的问题,提高除雪效率,设计了一种除雪铲分段式避障模块结构。利用Pro/E完成除雪铲铲刃的参数化建模,并结合ANSYS有限元分析除雪铲工作时除雪铲铲刃的应力应变情况,仿真结果显示其最大应力为3.82×10^(5) Pa,在其许用应力范围内,验证了该清洗/除雪一体化车除雪铲避障结构设计的合理性,为除雪铲避障结构的设计提供理论参考。

In order to effectively avoid the problem of amount increasing of snow left in the cleaning/snow removal integrated vehicles when they encounter small obstacles and to improve the snow removal efficiency,a type of segmented obstacle avoidance module structure for the snow removal shovel is designed in this paper.The parametric modeling of the snowplow blade is completed by using Pro/E;the stress and strain of the snowplow blade during working process are analyzed with ANSYS finite element method.The simulation results show that the maximum stress is 3.82,within the allowable stress range of snow removal shovel;thus the rationality of the design for the obstacle avoidance structure of snow removal shovel in the cleaning/snow removal integrated vehicle is verified.It would provide a theoretical reference for the design of snow removal shovel obstacle avoidance structure.
