“…A special type of torsion bar is what is being planned in order to decrease vibration on the driver's seat. A mechanism was employed in a stepped bar with a control arm, and the bar's stiffness could be adjusted to absorb loads spread to the driver's seat Analyses the shearing stress distribution, deflection, stiffness and dimensions for proposed stepped bar by using ANSYS and compared the results with numerical result achieved [14]. Torsion bar springs are dynamically loaded machine elements which can break due to fatigue [15].…”

This project focuses on the analyzing different materials for torsion bar suspension system for Tank T-55 for optimizing its performance for cross country mobility and ride comfort. This suspension system is aimed to improve wheel travel and angle of twist on all terrain conditions from rough to flat surfaces. The different materials studied are carbon steel and alloy steel for their suitability as torsion bar and proposed de-sign is accomplished through the material selection and analytical calculation with analysis for shear stress, total deformation and strain. alloy steel is considered as alternative material for torsion bar based on the result of its good strength in shear stress and store maximum energy in the case of strain energy.

“…Tyre deflection can be defined as the difference between un-sprung mass and road input, 𝑍𝑍 𝑢𝑢𝑠𝑠 − 𝑍𝑍 𝑟𝑟 . Static deflection of the tyre can be calculated using the formula, 𝛿𝛿 𝑡𝑡 = ((𝑚𝑚 𝑠𝑠 + 𝑚𝑚 𝑢𝑢𝑠𝑠 ) × 𝑔𝑔)/𝐾𝐾 𝑡𝑡 (7) Normal tyre load is calculated by the formula,…”

“…One configuration with best plane enforcement is then evaluated for mechanism variable output sensitivity and parasite error, thereby providing details about the design area. Rotational rigidity is determined based on numerical simulation in the in-plane rotational axis and tension [5][6][7][8]. In view of the linearity and nonlinearity method of the mechanism, a passive control system was tested.…”

New and better two-wheel models have increased demand today, with increased protection, comfort and performance. The human body gets exhausted, which contributes to back pain and neck pain because of the excessive use of bikes, wrong riding positions, poor weather and suspension system issues. The systems engineer would focus on the design of the vehicle suspension mechanism to minimise human discomfort. This research aims to study the feasibility of implementing a suspension system with active suspension for a two-wheeler by way of numerical modelling, simulation and analysis. First of all, the active suspension system for a 2 DOF system is modelled and analysed. The analysis done is frequency response analysis and time-domain analysis. The time-domain analysis is done using two road inputs; one is a bump input, which is designed according to the standards, and the other is a random road input. Then the two-wheelers were modelled as a 4 DOF model. The controller is modelled using optimal control theory. A linear quadratic regulator (LQR) controller is used because the system is assumed to have linear characteristics and the cost function of the system is quadratic. It is observed that suspension characteristics are improved by using the active suspension system in two-wheelers.

“…With the progress of science and technology, the discussion on the safety of car parts is becoming more and more a subject of debate. The structure of car seat backrest is one of key factors affecting the safety and comfort of the car [2,3]. Before leaving the factory, it is very important to inspect parts of the car seats, such as back curtains and springs of car seat backrests.…”

In order to solve the problems of slow manual inspection speed and low fault detection accuracy of car seat back parts, this article using Q company’s car seat back parts researches and designs a car seat back classification and quality inspection screening system. Firstly, SURF (speeded up robust features) is combined with the CNN (convolutional neural network) to classify three types of car seat backrests: A, B, and C. Then, to establish the spring hook angle detection model of the car seat back to detect the misfitting and omission of the Class A car seat back springs, experimental results showed that the neural network-based car seat back detection method proposed in this paper had a feature point mismatch rate, which is less than 1.5% in the classification and recognition of car seat backs. The recognition rate of the training sample was 100% and that of the test sample was 99.56%. The accuracy rate of detection when inspecting 50 car seat backrests reached 98%, and the test results showed that the system can effectively reduce labor costs and improve the detection efficiency of auto parts.
