Summary: In this study, an active vibration isolation controller is proposed to reduce the effect of vibrations on variations in the cavity length and improve the frequency stability of ultrastable lasers. The designed controller uses a state-differential feedback controller with a linear quadratic regulator (LQR) and a disturbance observer (DOB) to estimate source noise. Experimental results confirmed the feasibility and performance of the controller, as it effectively suppressed accelerations in the low-frequency band within 200 Hz and met the requirements of an ultrastable laser.

Summary: This study investigates the issue of excessive vibration in the cabin of a light vehicle when the air conditioning is turned on at idle speed, focusing on in-cylinder combustion caused by sudden load. Experimental analysis reveals that with the air conditioning on at low idle speed, the rise rate of cylinder pressure increases with fuel injection, resulting in increased engine vibration. Additionally, spectrum analysis of the vibration signal shows that the second-order vibration has the highest intensity, indicating poor vibration isolation effect of the rear suspension.

Summary: In this paper, a novel OTA method is proposed that considers the relationship between tolerance of machine tools' key parts and volumetric error. A volumetric error prediction model is established based on the bridge between geometric error and tolerance. Additionally, a Processing Simplicity Index (PSI) is introduced to replace manufacturing cost and a tolerance-PSI model is established. An OTA model is formulated to minimize volumetric error and maximize PSI. The feasibility and effectiveness of the method are validated through simulations and experiments.

Summary: This paper studies the electromechanical behavior of elliptical APAs by analyzing the multi-domain dynamics of piezoelectric stacks and compliant mechanisms using a novel electro-mechanical transfer matrix method. An analytical electro-elasto transfer matrix of piezoelectric stacks operating at the d33 mode is derived in the form of Taylor's series. The dynamic response spectrum of displacement and impedance for elliptical APAs is accurately captured by this electro-mechanical model, and different topologies of elliptical APAs are compared to suggest the optimal configuration.
