Motion Analyzer Optimises Machine Design


Rockwell's Motion Analyzer mechatronics tool optimises design for the automation and machine-construction industry. Application data can be accepted by the 3D CAD software Solidworks via the interface, directly from the OEM's mechanical design. An estimation of the loading then becomes superfluous and a genuine computation of the drive load is possible. Based on these data, the tool suggests a suitable drive, taking into consideration local conditions such as the supply voltage and the siting level. Motion Analyzer is able to carry out a comparison of costs and performance for various drive technologies.

This means that the user can select the variant most suitable to the machine's use. With the aid of the Motion Analyzer computation tool, the user can adapt the movement to the conditions in the mechanical system and optimise it for his specific application. There is an export function to the Logix controller so that the computed travel profile can also be executed later on the machine. The efficiency analysis shows, at a glance, in which part of the application the applied torque is present.

With the tolerance analysis each of the application parameters can be modified over a range. This means that an overview of the limits of the drive and also of the machine itself is obtained quicker and it is possible to determine the application modifications necessary for a drive solution. Similarly, the reaction of the drive can be simulated with the simulation tool.

In particular, the effects of less rigid or slack couplings are highlighted. From this, conclusions can be drawn about the feasibility of various design structures for the mechanical construction and adaptations carried out as required. A secondary effect here is the generation of settings for the control system. The tool calculates using exactly the same values as RSLogix 5000. This is used as a development tool for the whole control environment from Rockwell Automation.

This parameterisation is also transferred to the controller and the tuning of the servo drives is shortened. Rockwell Automation offers the optional integrated condition-monitoring solution Dynamix, which provides full vibration monitoring directly in the machine controller. The combination of vibration monitoring and machine analysis with a fast Fourier analysis allows preventive maintenance within the machine control. Motion Analyser takes the whole drive into account, analysing and optimising travel profiles and simulating the reaction of the system to control parameters.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
