Adaptability Analysis Of Special Vehicle JSQ6 To Hump

The position of the marshalling station in the railway station is very important,mainly because the marshalling station has the capacity for shunting operations.However,the stations that disintegrate in the road network and have heavy marshalling tasks,and at the same time,need to be equipped with a plane shunting hump,this is hump shunting system.The hump rolling operation is an important part of the marshalling station operation,an operation system that uses the potential energy of gravity to transform into kinetic energy.In the daily shunting operations,the hump saves a lot of time for the dismantling of the station,which greatly improves the work efficiency of the station.In recent years,with the continuous development of my country’s car manufacturing and transportation industry,especially after the state coordinated the promotion of transportation structure adjustment,and vigorously implemented the important measures of "Road to Railway",it is imminent to solve the problem of JSQ6 special vehicles rolling in each marshalling station,Because of the JSQ6 special vehicle model is special,has an extra-long change length,and has a structural design of a fish belly beam under the vehicle,in daily production,this type of vehicle must enter the shunting yard through the circuitous line or use the plane shunting.Greatly increase the time for disorganization marshalling and reduce the production efficiency of the station.Regarding whether the JSQ6 special vehicle can roll off and what conditions need to be met for the roll off operation,this paper has carried out specific research on this issue.After consulting the research literature,some scholars have conducted research in this direction.The author uses the methods of predecessors to integrate the existing and unconsidered factors,and focuses on the adaptability of the JSQ6 vehicle and the hump longitudinal section,and the JSQ6 model.The plane adaptability of the car and the marshalling yard are studied separately,and the influence of the longitudinal section of the hump is emphasized.First,establish a multi-objective planning model related to the distance from the bottom of the vehicle to the lowest point of the track surface,the efficiency of vehicle rolling and release,and the amount of renovation engineering,and analyze it theoretically.Then analyze the adaptability of the JSQ6 car and the hump plane,select the strand with small curve radius in the same direction and the strand with small curve radius in the reverse direction for analysis,and focus on the derailment coefficient and wheel load reduction rate.It is explained in theory.Subsequently,the actual station case was analyzed,and then the longitudinal section of the hump at station A was drawn based on the measured data of the hump longitudinal section,and the distance between the lowest point of the vehicle bottom and the track surface was measured through experiments.The plane rolling in the shunting yard mainly studies whether the JSQ6 special vehicle has the risk of derailment.The test selects the 16 and 20 tracks with the smallest curve radius,and the test data of the wheel-rail vertical force and wheel-rail lateral force obtained by the shear stress method are used in the test.Calculate the wheel load shedding rate and derailment coefficient,and analyze the test results of track 16 and track 20 according to the order of the test.Finally,analyze the measured data to find out whether the hump at station A is capable of releasing JSQ6 vehicles.possibility.After completing the above-mentioned experiments and theoretical analysis,the article gives an improvement analysis of the theoretical slope difference between the hump peak platform and the push slope acceleration slope,and proposes a feasible improvement plan.The plan is based on the fact that the hump is a station equipment that has a lot of influence.Try not to change the peak height and the net platform length of the peak,otherwise it will affect the unhooking operation of the station and cause decoupling or hooking.In addition,the height of the peak will affect the vehicles.After the disintegration of the rolling speed,raising it may cause the vehicle to overspeed,and reducing it may cause the vehicle to fail to reach the target area.Therefore,the article checked the hump capacity of the modified hump,and determined the safe rolling speed of the vehicle.After the completion of the theory and experiment,the DEA data envelopment analysis model is used to analyze the efficiency of hump decompilation at station A.The traffic flow at the station,the traffic flow at the hump disintegrated,and the traffic flow from the formation of station A are used as ordinary vehicles.To distinguish it from the JSQ6 vehicle,the amount of arrival and disintegration is used as the input index,and the departure amount of the marshalling is used as the output index.Find the key factors that affect the efficiency of hump de-compilation,analyze the possible impact of the output index changes on the output index,and put forward feasibility suggestions.The research results show that the research methods and conclusions proposed in this paper have certain practical significance and reference value,and provide decision-making basis for the research on the adaptability of JSQ6 and other special vehicles to hump.
