Parametric Design Study of McPherson Strut to stabilizer bar link bracket weld fatigue using Taguchi (DFSS) Approach

2021-04-06
2021-01-0235
Vehicle suspension parts are subjected to variable road loads, manufacturing process variation and high installation loads in the assembly process. Assembly of different parts can be done using bolts, welding, rivets, interference fit, adhesives etc., seam welding can be considered as such a process to connect more components and parts. Typical McPherson suspension system connects the strut assembly and the anti-roll bar using a stabilizer bar link (drop link) as an aid. Stabilizer bar link is connected to the strut assembly thru ball stud and clamped to a bracket which is welded to the outer strut tube. Testing’s at system level and vehicle level (RTS and Proving ground) are being conducted for fatigue assessment. Frequent cracks are observed in stabilizer bar link bracket welds in multiple vehicles affecting the functionality of the suspension system. Typically, a fillet (T) weld is created between the bracket and outer strut tube.

The basic reason is: the advanced positive trends in reliability and durability testing are implemented not enough. The paper considers also specific of positive trends and how they are implemented in practice, including different ways of these implementation. The author will be demonstrating the practical real examples of implementation positive trends in reliability and durability testing in different areas of engineering, physics, and mathematics in different countries. As a result, there is increasing reliability, durability, and safety, less complaints, recalls, and increase profit.

2021-01-0293
To overcome some drawbacks of using UHSS (Ultra High Strength Steel) in vehicle weight reduction, like spot weld HAZ (Heat Affected Zone) softening, hard machining and brittleness, a new solution of ultra-high stress strengthening was proposed and applied to the ridgelines of thin-walled structures in this paper. Firstly, stress distribution characteristics,laws of stress varying and compressed plate buckling process of the thin-walled rectangular beam under compression and bending load was analyzed in elastic-plastic stage by theory and FE simulation. Secondly, based on elastic-plastic buckling theory of the compressed plate and stress distribution similarity of the buckling process of thin-walled box structure, three factors influencing the limit resistance enhancement of thin-walled hat section beam were found in theoretical derivation, and the rationality and accuracy of cross section limit resistance prediction formulas were also verified by FE simulation.

Dynamic Transient Simulation To Predict Durability Loads From Road Load Profile Under Linear Assumptions

2021-04-06
2021-01-0831
Durability assessment for vehicle structures requires load inputs from different road profiles. These load inputs can be in terms of force, acceleration and displacement and can be acquired from road load data. But if a program is in its early stage or lab facility is limited then acquiring these load inputs takes time and sometimes not feasible also. In this scenario, we can predict the durability load inputs from road load profile virtually using dynamic transient simulation with linear assumptions. These input scan be further used for quantitative or comparative validations of durability assessment for multiple sets of road load or design data. This paper emphasizes on the measurement of inputs for durability assessment from road load data using dynamic transient simulation with few assumptions.

Dr. Boris Y. Ganelin, Boris B. Ganelin Abstract The lack of understanding of the physics of fluid-structure interaction, loads and vibration of high speed aerial/rocketry vehicles is addressed in this paper. This extraordinarily difficult problem is complicated and difficult to ascertain. One from fundamental cornerstones of aforementioned problem is accurate aerodynamic predictions of the vehicle’s characteristics due to their significance in determining vehicle’s performance, stability and reliability. However, accurate aerodynamic predictions are unattainable in the framework of modern fluid dynamic paradigm based on boundary layer concept. The mandatory conditions for authentic theory-based and experimental aerodynamic modeling are formulated.

Application of an Approach to Assess the Sensor Perception Reliability of Automated Driving Vehicles from Fleet Data

2021-04-06
2021-01-0080
One major requirement for safe automated driving is a reliable environment perception. For evaluating the reliability of the vehicle's environment perception, field tests offer testing conditions that come closest to the vehicle's driving environment. However, establishing ground truth values in field tests is associated with a huge effort. This motivates the development of a procedure for learning the vehicle's perception reliability without the need for a ground truth which would allow to learn the perception reliability from fleet data. One step towards the evaluation of the vehicle's perception reliability from fleet data is a method to obtain the reliabilities of the individual perception sensors. In Berk et al. (2019), we proposed a method based on Bayesian inference to determine the sensor perception reliability without the need for a ground truth. The model utilizes the redundancy of sensors to learn the sensor's perception reliability with Markov Chain Monte Carlo (MCMC).

Object detection and tracking for autonomous vehicles in adversary weather conditions

2021-04-06
2021-01-0079
Object detection and tracking is a central aspect of perception for autonomous vehicles. While there has been significant development in this field in recent years, many perception algorithms still struggle to provide reliable information in challenging weather conditions which include night-time, direct sunlight, glare, fog, etc. To achieve full autonomy, there is a need for a robust perception system capable of handling such challenging conditions. In this paper, we attempt to bridge this gap by proposing an algorithm that combines the strength of automotive radars and infra-red thermal cameras. We show that these sensors complement each other well and provide reliable data in poor visibility conditions. We demonstrate the advantages of a thermal camera over a visible-range camera in these situations and employ YOLOv3 for object detection.
