Design And Research Of A Quasi-high-speed Refrigerated Trucks

Refrigerator car is a special railway equipment, and the development course had passed through from ice-cooled refrigerator to mechincal refrigerator. But ,all of them are grouped with the freight trains. Although many measure have been adopted to improve the transport speed of good, but it will take longer period comparing with the same occasion of overseas. And the passenger car has shown it advantages in the speed-improving today . A short journey with regularity start and arrived time ,the passenger cars had attracted many people and a great deal of goods. With the continuous improvement of the people life, Market of the little batch and hight additional value cargoes are becoming bigger and bigger. So to develop a new refrigerator car which can be grouped with passenger trains is another method for refrigerated cargoes transport. Type 160 km/h refrigerator car is properly meet the requirement of this refrigerated transport market.Main research process of Type 160 km/h refrigerator car is expatiated in detail in this paper. Not only analyse the main structure of vehicle and the main performance parameter, but also calculate the strength and stiffness of the car by using the software of ANSYS. And dynamic simulation calculations are made by special dynamics simulate software. In the end ,all the theoretic analyses or caculations are proved reasonably by the strength test, air-tightness test, thermal insulating properties test and dynamics test of the vehicle.Finally, we can draw the conclusions: structure of the type 160km/h refrigerator car main body is reasonable, strength and stiffness of the vehicle meet the requires of the standard of TB/T1335-1996< Railway vehicles - Specification for design of the strength and accreditation test>. Air-tightness test and thermal insulating properties test have proved that the expectable purposes which we have expected. Index of running stability, stability against overturaing,stability against derailment and coefficient of derailment of the car meet the requires of the standard of GB/T5599-1985< Railway vehicles - Specification for evaluation the dynamic performance and accreditation test>. Type SW-160 bogie is suitable for this refrigerator car to group with the passenger car too.
