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.

Key words：hydraulic brake; finite element; engineering vehicle

礦用工程車上的液壓制動(dòng)裝置是保證工作人員生命財(cái)產(chǎn)安全的重要裝置[1-5]，良好的裝置不僅需要能夠在礦山中惡劣的環(huán)境中保證良好的制動(dòng)性，而且能夠提升礦車的工作效率[6-11]。（剩余2844字）
