The invention discloses a variable-rigidity passenger and freight car platform which is composed of an upper-layer car platform body, a lower-layer car platform body and a connecting piece layer between the upper-layer car platform body and the lower-layer car platform body, and the connecting piece layer between the upper-layer car platform body and the lower-layer car platform body is a variable-rigidity switching layer. In the passenger state, sufficient rigidity and damping are provided, the passenger carrying requirement is met, meanwhile, vibration and noise are reduced, and the riding comfort is better. And in the freight state, higher rigidity is provided, and the passenger and freight dual-purpose requirement is met.
本发明公开了一种可变刚度客货两用轿底,由上层轿底、下层轿底及上下层轿底之间的连接件层构成,上下层轿底之间的连接件层为可变刚度切换层。本发明在乘客状态时,提供足够的刚度和阻尼,满足载客需求的同时,降低振动和噪声,乘坐舒适度更好。在货运状态下,提供更大的刚度,满足客货两用的需求。
