The invention provides a locomotive cab floor structure, a cab and a locomotive, and relates to the technical field of vehicles. The locomotive cab floor structure comprises a floor body and a supporting sound-absorbing layer, the supporting sound-absorbing layer is arranged in the floor body, and noise sound waves can enter the supporting sound-absorbing layer through the floor body and oscillate in the supporting sound-absorbing layer to be used for reflecting and absorbing the noise sound waves. The supporting sound-absorbing layer is arranged in the floor main body, and the supporting sound-absorbing layer has a supporting effect. Meanwhile, after noise sound waves pass through the floor body and enter the supporting sound absorption layer, the noise sound waves oscillate in the supporting sound absorption layer, the propagation path of the noise sound waves is prolonged, in the repeated reflection and oscillation process of the noise sound waves, energy of the noise sound waves is gradually consumed, the effect of noise absorption is achieved, and the silencing effect is improved; therefore, the situation that noise sound waves are upwards transmitted to the cab body is reduced, and the comfort of the environment of the cab body is improved.
本发明提供一种机车司机室地板结构、司机室及机车,涉及车辆技术领域。该机车司机室地板结构包括地板主体和支撑吸音层,支撑吸音层设置于地板主体内,其中,噪音声波能够通过地板主体进入支撑吸音层内,并在支撑吸音层内震荡,用于噪音声波的反射和吸收。支撑吸音层设置于地板主体内,支撑吸音层起到支撑效果。同时,噪音声波在通过地板主体后进入支撑吸音层之后,噪音声波在支撑吸音层内震荡,噪音声波的传播路径延长,噪音声波在反复反射和震荡过程中,噪音声波的能量逐渐被消耗,起到噪音吸收的作用,提高消音效果,从而减少噪音声波向上传递至司机室本体的情况,提高司机室本体环境的舒适性。
