...Yonghua Xiong; Lei Tian; Tofael Ahamed; Bin Zhao In this article, the development of the Reconfigurable Data Acquisition Vehicle (R-DAV) that has a high performance as a wheeled mobile robot is presented. The R-DAV is designed to monitor and manage the growing status of bio-energy crops...

...Daniel Wehrwein; Zissimos P. Mourelatos Quality and performance are two important customer requirements in vehicle design. Driveline clunk negatively affects the perceived quality and must be minimized. This can be achieved using engine torque management, which is part of engine calibration. During...

... and a three-level hierarchical model used in vehicle suspension systems design. Comparison of GSSIs for main effects in Example 1 Figure 5 illustrates the GSSIs for the main effects of the four input variables using the proposed HSSA method and the AIO method. The y -axis indicates...

... to distribute the sampling points uniformly over the entire design space. The Root Mean Square Error (RMSE) is used as the error indicator. Convergence rate, widely used in the arena of the finite element method for evaluating new element’s performance, was exploited in this vehicle impact example. 16 03...

... the interactive negotiations among the design engineering groups. A direct synthesis (DS) method was developed to support the negotiations by combining adaptive and interactive modeling system based surrogate modeling with a set-based “zoom-in” approach. A vehicle frontal structural system design example is used...

...Chul Kim; Paul I. Ro In this study, an approach to obtain an accurate yet simple model for full-vehicle ride analysis is proposed. The approach involves linearization of a full car MBD (multibody dynamics) model to obtain a large-order vehicle model. The states of the model are divided into two...

...Gang Deng; Tsutomu Nakanishi; Masana Kato In recent years, power transmission gears for vehicles run at higher speeds and loads and are accompanied by very high surface temperatures. Under such a high surface temperature condition, the surface strength cannot be evaluated correctly only by the use...

...Xiaobo Yang, Researcher; Subhash Rakheja, Professor; Ion Stiharu, Associate Professor A yaw plane model with limited roll-DOF of a five-axle tractor semitrailer is developed to study the open-loop directional dynamics of the vehicle. A driver model incorporating path preview, low and high frequency...

...Paul C. Wiers, Director; Anoop K. Dhingra In the drag racing environment, maximizing tractive effort is essential to competitive performance. Anti-squat is a transient vehicle suspension parameter which can dramatically affect tractive effort available at the motorcycle drive tire. This paper...

... parameterizations of the constraint manifold that must be often modified during a simulation. In this paper it is shown that, for vehicle multibody systems, generalized coordinates that are dual to suspension and/or control forces in the model are independent for the entire range of motion of the system. Therefore...

...B. J. Choi; S. V. Sreenivasan This paper presents a geometric approach for solving the force distribution problem in active wheeled vehicles (AWVs) moving on uneven surfaces. Here an active vehicle is defined as a system that includes independent actuators for all its internal joints. In general...
