基于ANSYS的多层振动筛侧板开裂研究

Study on Cracking in Multi-Layer Vibrating Screen Side Plate Based on ANSYS

针对某厂家生产的沥青搅拌设备多层振动筛的侧板开裂问题,提出通过增大振源板与侧板的接触面积的解决方案,在ANSYS中对改进前后的结构模型进行热固耦合仿真分析,并进行相关理论计算。结果表明,该改进方案能有效降低振源板与侧板铆钉圆孔周围的应力,且接触部分整体的应力分布较均匀,能防止振动筛侧板开裂。

Aiming at the problem of side plate cracking of multi-layer vibrating screen of asphalt mixing equipment, this paper puts forward a scheme to solve the cracking problem by increasing the area of the vibration source plate and side plate. Then it makes a simulation analysis of thermosetting coupling for the structure model before and after the improvement in ANSYS and also makes the relevant theoretical calculation. The result shows that the improved scheme can effectively reduce the stress around the round hole of the heat source plate and side plate rivet with the uniform stress distribution of entire contact part and prevent the cracking problem of vibrating screen.
