Abstract:
Based on AMESim, by the analysis of the Conveyor Belt four discrete model, Select and built the Kelvin-Voigt model which is simple and applicable, by comparative analysis of drawing on four commonly used to start the acceleration (uniform acceleration, triangle acceleration, trapezoidal acceleration and the Harrison), Select the Harrison speed as the starting acceleration and Using AMESim to establish the starting model of acceleration.Keywords:

Acceleration behaviour of vehicles is important for various applications. The delay caused while leaving the signalized intersection, depends on acceleration capability of a vehicle, among others factors. Acceleration of motorized three wheelers merits attention since though they accommodate passengers similar to car; they accelerate differently as compared to car. Therefore, objective of this study is to understand the acceleration behaviour of Motorized Three Wheelers. It is observed in this study that acceleration rates of Motorized Three Wheeler differ from reported acceleration rates in literature. The maximum acceleration rate, speed at maximum acceleration and distance travelled during acceleration maneuver are found to be sensitive to maximum speed achieved during acceleration maneuver. On finding existing acceleration models to be insufficient to explain the acceleration behaviour of Motorized Three Wheelers, new models are proposed and validated.

To solve the overshoot of acceleration of traditional model,a model with variable desirable distance for vehicle following is presented,which considering limitation of the acceleration.The linear stability theory is applied to the proposed model,the result of stability is different from the Bando′s.Through the simulation result,it is found that when the maximum acceleration is reasonable,the stability of the traffic flow is better with the increase of the value of maximum acceleration.While the traffic flow becomes unstable when the maximum acceleration is too large.The proposed model is favorable to keep the traffic flow stable.

As the belt conveyor towards long distance, large capacity and high speed in the direction of development, The belt conveyor dynamic characteristics became more and more obvious, the dynamic characteristics of the starting process in order to better understand the large belt conveyor, and the different starting acceleration of belt conveyor impact size, To determine the optimal starting acceleration, introduces the calculation formula of ideal starting acceleration for four kinds of belt conveyor, Put forward on belt conveyor and its starting acceleration model was established based on the AMESim software library of mechanical signal The starting process of belt conveyor is simulated by using AMESim software, Scheme for determining the optimal acceleration, Through the comparative analysis of the simulation results, It is concluded that the impact of Harrison acceleration on the conveyor belt is minimal during the starting process, taking Harrison as the object of starting acceleration , the simulation of different start time is carried out, The results show that the longer the starting time, the smaller the impact of the starting process on the conveyor belt.
