新型机车的发展方向必须是在原有机车总重量的前提下具备更高的输出功率和提高运行速度。由于电气设备的重量占机车总重量的比重很大,所以车体设计人员不得不开发一种更轻型的结构,以便适应更加严格的要求。到目前为止,机车车体主要是采用钢结构。目前,瑞士的机车和机器制造厂已进入了新的设计领域,使用玻璃钢制造出了SBB The direction of development of new locomotive must be in the original total weight of the locomotive with the premise of higher output power and increase operating speed. As the weight of electrical equipment accounts for a significant portion of the total weight of the locomotive, bodywork designers have to develop a lighter structure to accommodate the more stringent requirements. So far, locomotives are mainly made of steel. At present, Switzerland’s locomotives and machine builders have entered new design areas, using FRP to manufacture SBB
