Vehicle needs suspension and steering systems with different features to fit different driving conditions. In normal straight driving condition, soft suspension and heavy steering systems are needed to achieve better ride comfort and straight line driving stability; in turning conditions, hard suspension and lightweight steering systems are needed to get better handing stability. The semi-active suspension system with Magneto-Rheological dampers can improve the ride comfort and handling performance of vehicle. Electrical power steering system is developed rapidly due to its portable and flexible operations as well as stable steering performance. In this paper, the features of electrical power steering and semi-active suspension systems have been done a more in-depth study, and an integrated control strategy was proposed to achieve the coordinated control of these two electric control systems arises in order to improve the ride comfort and ensure the steering stability in cornering situation. In a well on the basis of experimental data, the mathematical model of electrical power steering and semi-active suspension systems were adopted to predict the characteristics of these two electric systems. The numerical simulation results show that the integrated control strategy is effective and successful in improving the overall performances such as rapid electrical power steering and good body post regulation. The primary goal of this paper is to create an effective, reliable and safe integrated control strategy for steering and suspension systems that improves the ride comfort as well as handing stability. © 2012 SAE International.

In order to solve the problem of slow flame propagation in a spark-ignition engine fueled with compressed natural gas (CNG), the influence of in-cylinder flows on combustion process was investigated in CA6SE3-21E4N CNG-engine by means of numerical simulation and experiment. The status of in-cylinder flows from intake to expansion stroke was described by computational fluid dynamic tool, which revealed that the in-cylinder flows were one of the main reasons of slow burning rate. Therefore, a special-shaped combustion chamber called Cross was used to improve the in-cylinder flows. The results showed that peak turbulent kinetic energy of Cross was 43.9% higher than that of original combustion chamber called Cylinder during the late compression period at 1450 rpm 100% load. The combustion parameters, brake specific fuel consumption (BSFC) and regulated emissions were obtained by means of experiment. At 1450rpm 25%, 50%, 75% and 100% load conditions, the ignition delay of Cross was longer than that of Cylinder, moreover, the Cross produced averagely 5.75°CA shorter combustion duration. The BSFC of Cross was on an average of 4.3% reduction at 1450 rpm as well as the HC and CO emissions were reduced whereas the NOx emissions were significantly increased. © 2013 The Korean Society of Automotive Engineers and Springer-Verlag Berlin Heidelberg.

A two-stage sequential turbocharging system was proposed in order to meet the power output requirements for diesel engine within the altitude range from zero to 5 500 meters. Based on the required power recovery of CA6DL2 engine, the specific parameters of the turbocharging system were calculated and the low-pressure turbocharger was chosen. The software GT-Power was used to calculate the engine's performance at different altitudes. The simulation results show that, due to a good match with the two-stage sequential turbocharging system, the engine power can be recovered to 80 percent at 5 500 meters while keeping no change at sea level.

The steering torque variation which is an important evaluation index of the vehicle handling stability directly influences the feeling of driving. The objective of this chapter is to optimize the hard points and the phase angle of steering column assembly in order to reduce the torque variation to the minimum, and improve the vehicle handling stability. In this chapter, the formulas for accurate calculation of the angular velocity ratio and the torque variation in double cross universal joints system are deduced according to the transmission analysis of single cross universal joint. Based on the study of the formula for approximate calculation of the rotational angle deviation in double cross universal joints system and the calculation of the torque variation using MATLAB software, an effective optimization method of the phase angle which could be applied to reduce the angular velocity ratio and the torque variation is obtained. The torque variation could be calculated exactly and reduced to the minimum by using the optimization method and formulas in the early stage of steering column assembly layout. The formulas and optimization method could also be applied to other cross universal joints transmission system. © 2013 Springer-Verlag.

To predict vertical step passability of wheeled vehicle and get driveline torque, this paper presented a unified obstacle crossing model. The model could simulate climbing process of any given axle of a vehicle with any axles. Factors such as adhesion coefficient difference between climbing wheel and rolling wheel, suspension bound and rebound limits, wheel liftoff were considered. Passability criteria of simulation results was discussed. The model was validated through tests. Influence of suspension bound limits on driveline torque was analyzed. ©, 2015, China Mechanical Engineering Magazine Office. All right reserved.

With the development of the car industry and the rising of consumer's requirements for comfort, brake noise gradually becomes one of the important factors to appraise the comfort of vehicle. This paper, aiming at solving the noise problem of the passenger car, researches the mechanism of brake noise's generation and the ways to optimize it in order to reduce the noise. The brake noise is tested according to the road test standard. The frequency and intensity of the noise are recorded in the vehicle test. At the same time, the relation of speed and the noise's frequency is recorded. The brake noise is divided into Squeal noise and Groan noise based on the test results of the car. Squeal noise: It is important to collect more information in the dynamometer which used suspension assembly to analyze the character of noise. The noise mechanism is analyzed and the optimum direction is found through the computer CAE technique. Groan noise: Based on the calculation and analysis of the test results, the main influencing factors of the noise are found and the optimum scheme is designed. Finally the performance of brake noise is validated in the dynamometer and the vehicle test. Computer analysis and test results show that Squeal noise is caused by the resonance of the brake system. In this paper, brake noise is reduced by reducing the stiffness of the brake disc by an average of 5%, optimizing the inherent character of the brake system and improving the stability of the brake system. Based on the test and the analysis, the main cause of the Groan noise is that the structure of brake pad and brake disc's ventilation is designed with defects. Groan noise is related to the structure of brake pad and brake disc's ventilation. It is effective to reduce noise by optimizing brake pad's structure. © Springer-Verlag 2013.

Wind noise, an aeroacoustic phenomenon, is an important attribute that influences customer sensation of interior quietness in a moving vehicle. As a vehicle travels faster, occupants' sensation of wind noise becomes increasingly objectionable. The purpose of this work is to investigate the increase of wind noise level perceived by a driver in response to an increase in wind speed. Specifically, it explores how much the level of wind noise at the DOE (driver outboard ear) would vary in response to a change in wind speed based on the test data obtained in a wind tunnel from ten vehicles that belong to several different passenger vehicle segments. The first part of this work studies the change of the SPL (sound pressure level) in response to a change in wind speed U. It shows that the SPL(dBA) approximately scales to U5.7 at the DOE and to U6.3 in the far-field, which could be interpreted as the dominance of dipoles. The second part of this work looks into the scaling of loudness measured in Zwicker sones that represent the human auditory sensation of wind noise level. It shows that the human perception of the wind noise loudness scales to U1.7 approximately, which indicates that the wind noise loudness sensation is doubled when the vehicle speed incurs a 50% increase.
