Bending operations are frequently used to produce sheet metal components. Spring-back is an issue in sheet metal forming processes and some times is a principle problem for producing precise components. This is more important if some kind of cuttings exists on the bending surfaces. Experiments show that punched holes on bending surfaces affect the value of the spring-back. In this paper the spr...

Large herbivore populations respond strongly to remotely sensed measures of primary productivity. Whereas most studies in seasonal environments have focused on the effects of spring plant phenology on juvenile survival, recent studies demonstrated that autumn nutrition also plays a crucial role. We tested for both direct and indirect (through body mass) effects of spring and autumn phenology on...

Increasing competition and innovation in automobile sector tends to modify the existing products by new and advanced material products. A suspension system of vehicle is also an area where these innovations are carried out regularly.Leaf springs are one of the oldest suspension components that are being still used widely inautomobiles. Weight reduction is also given due importance by automobile...

In order to study of variation and correlation between yields and yield components in oilseed rape, an experiment was designed using line×tester method. Fifteen hybrid derived from crosses of three spring type and high yielding testers (SPN34, RGS003, SPN1) with five spring lines with moderate yield (SPN3, SPN9, SPN36, SPN30, DH4) were tested using a randomized complete blocks design with two r...

This paper discusses two approaches to modeling helical suspension springs for use in a dynamic finite element compressor model. The first approach represents the spring's stiffness characteristics with a simple spring element matrix. The appropriate spring constants are calculated using a separate finite element model of the spring. The spring modeling procedure is described and supplemented w...

Sowing time, as an element, is important to improving the adaptation of cultivars environmental conditions and achieving high seed yields. The field experiment was conducted from 2018–2019 at Experimental Station Vytautas Magnus University Agriculture Academy. experimental design included treatments with different sowing dates: eight dates in 2018 10 2019. first spring rapeseed carried out when...

We describe the locomotion dynamics of a biomimetic robot and compare them with those of its exemplar: the cockroach. The robot is a small (0.275kg) hexapod created using a layered manufacturing technique that allows us to tailor the compliance and damping of the limbs to achieve passive stabilization similar to that observed in insects. The robot runs at over 3 body-lengths per second (55 cm/s...
