A PDE-constrained optimization framework is employed to solve the inverse problem, aiming to minimize the misfit between measured and computed deflections, with regularization terms for control variables. The material profiles to be reconstructed include the elastic modulus of the beam and the stiffness of the Winkler foundation. The optimization process involves augmenting the objective functional into a Lagrangian functional and enforcing its stationarity to iteratively solve the state, adjoint, and control problems. Numerical examples examine three cases: (1) reconstruction of the beam’s elastic modulus with known foundation stiffness, (2) reconstruction of the foundation stiffness with known beam modulus, and (3) simultaneous reconstruction of both properties. Results show that both profiles can be accurately reconstructed simultaneously using a single set of measured deflections, without requiring subjective intervention.

The system consists of a flipping base and a snake-arm manipulator. It offers high flexibility but also presents great difficulties in solving inverse kinematics. In this paper, we propose a synergistic motion scheme for the snake-arm system to pass through small holes into confined spaces. Firstly, we present the kinematic model. Next, to guide the snake-arm manipulator smoothly into indoor spaces, we propose a dynamic path planning method. We divide the following path into three parts: obstacle avoidance path, feeding path, and transition path. Each part is planned individually, and a procedural method is used to combine them. Unlike traditional static paths, the feeding path and transition path can adaptively adjust as the snake-arm system moves. To ensure strict adherence to the dynamic path during follow-up motion, we propose a dynamic path synergistic following algorithm specifically designed for this type of system. Compared with existing algorithms that follow static paths, the new algorithm will not be constrained by the single feed direction of the snake-arm system. Simulation tests verify the effectiveness of the algorithm, which achieves an endpoint positioning accuracy of 10⁻⁷ mm for the snake-arm manipulator. Additionally, it expands the workspace of the snake-arm system from 1.59 m³ (horizontal mode) to 7.19 m³, while reducing outdoor height occupation by 21.54 % compared to vertical motion.

The ultrasonic deep cold rolling (UDCR) technique can induce uniform compressive stresses on the machined surface with a great depth, which leads to improved surface integrity and, consequently, enhanced fatigue performance of the components. However, the latent nature of residual stresses makes it challenging to assess and measure the applied stresses accurately. In order to address this issue, a numerical approach is proposed to investigate the characteristics of the surface layer in the UDCR process. The mechanism of the UDCR process induces severe plastic deformation in the surface layer by applying static force and ultrasonic shock vibration. Therefore, taking TC4 titanium alloy as the example, the effects of UDCR parameters such as static force, ultrasonic rolling amplitude, ball diameter, feed rate, and friction coefficient on residual stress and surface deformation were investigated by finite element modeling and simulation. A validation test was conducted, and the results were compared to confirm the validity of the finite element model. The finite element simulation results show that increasing the static force and vibration amplitude significantly enhances surface deformation and the depth of the compressive residual stress layer, while the feed rate and coefficient of friction have a negligible effect on the residual stress distribution and surface deformation. Additionally, increasing the ball diameter notably reduces surface compressive residual stress, maximum compressive residual stress, and penetration depth.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"207 ","pages":"Article 103942"},"PeriodicalIF":4.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
