The computed pretightening force of bolt and washer size reach the prefigurative result in the construction test, but the pretightening force of bolt was decreased obviously by the time increase for matrix relaxation effect, and then tending towards a stable value.
This paper have analyzed the Australian/New ZealandWasher Energy Standard : AS/NZS 2040.1:1998. The paper alsohave compared main difference between Australian Washer En-ergy Standard : AS/NZS 2040.1:1998 and Chinese Standards:GB/T4288-2003 on testing methods.
The automatic control system of auto washer based on fuzzy control with single-chip computer AT89C51 can be implemented by intelligence control,so the quality of washing is improved and the source is saved.
This paper briefly introduces controlling processes of alarm timing and principles of Electronic Timing Alarm Control System(ETACS) to the intermittence of wiper motor,washer,seatbelt,rearview mirror heating and preheater systems.
简要介绍ETACS(Electronic Timing Alarm Control System)对刮水器电机的间歇、洗涤器、安全带、倒车镜加热、预热器系统等的定时报警控制过程及原理。
The actuator is a cylindrical Nitinol washer that expands axially when heated.
The best results with the compression-trained washer were achieved after homogenization at 1073 K where the compression training deformation was -10.4%, the lowest applied.
This paper evaluates the performance and engineering aspects of 44Ti-47Ni-9Nb alloy in a pretensioning washer application.
Compressive training of the shape memory alloy washer
This technique is based on the Marciniak biaxial stretch test using a single punch/die configuration, but the specimen and washer geometries have been modified in order to achieve failure in both drawing and stretching deformation modes.
