1、全地形车辆转向节的有限元分析外文文献翻译中英文翻译外文翻译Analysis of Steering Knuckle of All Terrain Vehicles (ATV)Using Finite Element Analysis Abstract: Steering knuckle is the most stress sustaining and critical component of All Terrain Vehicle (ATV). Steering knuckle is the pivot point of the steering and suspension system

2、,which allows the front wheels to turn and also allow the movement of suspension arms motion.The light weight and high strength component is always in demanding for racecar application.Lightweight and optimized design of steeringknuckle is proposed to use for a BAJA SAE INDIA off road racecar. Due t

3、o the failure in knuckle in terrain vehicle after some instances, it has to be modified for better performance. The 3D CAD model created by using CATIA V5and static as well as model analysis carried out in ANSYS 12 to understand its behavior under operating conditions. All test for frame was carried

4、 out on aluminum alloys 6061-T6 & for spindle EN8. The paper discusses the FE analysis of existing and modified Steering Knuckle.1. Introduction All-terrain vehicle is design for BAJA event is organized by SAEINDIA and Mahindra &Mahindra in the 2015. The object of the competition is to simulate real

5、-world engineering design projects and their related challenges. Each team is competing to have its design accepted for manufacture by a fictitious firm. Each teams goal is to design and build a single-seat, all-terrain,sporting vehicle whose structure contains the driver. A steering knuckle is a co

6、mponent over which a wheel hub has been mounted and support for steering and braking which operating under very high stress condition. Steering knuckle is not a standard part of terrain vehicle component but it may be change for every racecar. Thus, the design may vary to fit all sorts of applicatio

7、ns and suspension types. A CAD model of existing steering knuckle is shown in figure 1 is applied in the racecar as shown in figure 3. Finite element analysis(FEA) is a method for predicting how a product reacts to real-world forces, vibration and other physical effects. FE analysis shows whether a

8、product will wear out, break, or work the way it designed. The advanced optimization techniques help to explore the light weight architecture. Rajendran et al discusses the process of designing light weight Knuckle from scratch which can be applicable for many casting components. To derive the optim

9、al load path required for the major load cases a topology optimization is performed on the design volume and prepare a concept model from the topology results generated. The model is verified for all the required extreme loads & the durability load which helps for significant mass reduction from mod

10、el. Chang and Tang presented an integrated design and manufacturing approach that supports shape optimization of structural component. The approach starts from a primitive concept stage, where boundary and loading condition of structural component are given to the designer. Topology optimization is

11、conducted for a structural layout. A 3D tracked vehicle roadarm is employed to illustrate overall design process and various techniques involved. According to B.Babu et al, Steering Knuckle plays major role in many direction control of the vehicle it is also linked with other linkages and supports t

12、he vertical weight of the car. Study involves modelling of the steering knuckle with the design parameters using the latest modelling software, and also it includes the determination of loads acting on the steering knuckle as a function of time. This is done for finding out the minimum stress area.

13、Chang Yong Song discusses reliability-based design optimization (RBDO) of an automotive knuckle component under bump and brake loading conditions. The probabilistic design problem is to minimize the weight of a knuckle component subject to stresses, deformations, and frequency constraints in order t

The finite element analysis is conducted using ABAQUS, and the probabilistic optimal solutions are obtained via the moving least squares method (MLSM) in the context of approximate optimiza

15、tion. In the present study, design of a durable and reliable steering knuckle for a racecar being an ultimate aim to be achieved. Development of racecar components tied with the regulations drawn by the organizer. In existing design of knuckle, which has very less weight, but at the time of race a s

16、teering arm has separated from the knuckle due to low strength of knuckle and high strength of bolted joint as shown in figure 2. While steering an arm pulls knuckle towards a car for turning, so it should be assembled with the knuckle to strengthen a steering and braking mechanism. In proposed design, a single piece of knuckle includes the steering arm and brake caliper and not provide any bolted joint to improve its strength and attached to knuckle directly. Figure
