摘 要：本文設(shè)計了一種針對礦用工程車輛的新型濕式液壓制動裝置，靜止時通過活塞擠壓摩擦片與制動片實現(xiàn)制動效果，運行時液壓油注入抵消彈簧壓力使車輛運行。然后針對5t工程車輛，匹配了摩擦副的具體參數(shù)，并對處于長時間受壓工作狀態(tài)的活塞進行了有限元分析，分析結(jié)果表明，對于5t工程車輛，其強度滿足要求。

Brake design and virtual verification of mining engineering vehicles

Abstract：In this paper， a new type of wet hydraulic brake device for engineering vehicles is designed. The piston squeezes the friction lining and the brake lining to achieve the braking effect when it is stationary. When running， hydraulic oil is injected to offset the spring pressure to make the vehicle run. Then for the 5t construction vehicle， the specific parameters of the friction pair are matched and the finite element analysis of the pistons under long-term pressure working conditions has been carried out. The analysis results show that for a 5t construction vehicle， its strength meets the requirements.
